Fantastic! Now I know ground is just the negative side of the battery. I wish other people would have said that and not left me confused.
Unfortunately, no. This video is misleading and a little wrong; ground is more complicated than that. Here is a more complete explanation. ruclips.net/video/KXjSSvIrKUw/видео.html
Well, in a simple case. But if you imagine more batteries in series, then it's the last one in that will represent the theoretical ground, theoretical, as it is not really grounded, so between that and the real ground point there can be potential difference.
@@fulesmackofule can u explain to me in that case , where is the real ground point?
@@datle5585 Well, I assume if negative is connected to the real ground too, then it would be. But it is not 0V potential ever as charged by many things, e.g. particles from space. But good enough. :)
Hopefully it is clarifying.

Splendid! Couldn't quite understand the other videos or explanations on this thingie, until I found your video.
He's said it right in many other videos(how battery works - electronics basics 3, for example). He may has slipped here but it happens. We just have to point it out to him but not attack him.
Great work, keep it up!
Mate, you are doing a great job! This is probably the best channel in RUclips regarding electronics. I admire how simply you explain otherwise rather difficult concepts. Thank you, and I hope you keep this channel rolling. :)
Well thank you for your kind comments :) I intend to keep this channel going with no exception.

After 10 years of seeing electrical circuits and scratching my head it finally made sense!
Conventional current flows from positive to negative voltages. In reality, electrons flows from negative to positive..
here in the video says the electrons go otherwise.. my head blew
exactly my thought
The presenter quite plainly stated that he was speaking of conventional flow.
the lack of an electron at a position where one could exist in an atom or atomic lattice, so the empty spaces that electrons leave while moving to the positive side are called holes is the positive current or conventional current or hower you want to call it.
😂 I was thinking the same 😂
Braden Z Agree, and it is very important to have this straight. For example, one can’t understand vacuum tubes or transistors without actually knowing which way electrons and ‘positive holes’ flow. So, in this example, or any ground, electrons are actually ‘sucked out’ of the ground.
Thank you for your explanations. I'm just beginning to learn about electronics and I find your channel very useful.
A lot of viewers are jumping on the "electron flow" direction. (1) In the beginning he told that it is conventional current direction. (2) Just think those moving dots as +ve charges.
very simple
Thank you for one of most lucid explanations of ground - I think I finally understand the concept after close twenty years trying to learn electronics.
I'm very glad I could enlighten you :)
ruclips.net/video/upaVO_SMAQM/видео.html 🙏👍
SO FANTASTIC VIDEO man !!! I was spending 5 days thinking " this is an open circuit , how the hell can it run in the first place " , google all over the place but they just explain that ground is for voltage reference , but no one have explained it's very core meaning . Keep on the good work!
a very good demonstration with the right implementation of every circuit. Subbed !
Thanks!
Just will tell...simply superb video...thanks
I really like your video but there seems to me a misconception about electrons:
1:05 electrons don't ever get rid of their charge (unless they meet positrons which doesn't usually happen in circuits)
and they don't carry any kind of "additional charge" they could get rid of
but they carry specific quantity of charge - the elementary charge
this was discovered in 1909 by Robert Millikan.
More here: en.wikipedia.org/wiki/Elementary_charge
5:16 electrons do always carry elementary charge
There is a very serious basic flaw in this video. The author said electrons flows from the +ve terminal to the negative; it is wrong in all manner! The current flow from +ve to -ve is only a historical convention - thus called conventional current flow. We now know current is actually a flow of electrons that goes from the -ve terminal to the +ve (of a battery). In AC current direction reverses every half cycle.
I suppose what he should have stated is that the difference of potential held by that excess charge is lost when they return to the earth. But apparently, even that is not a completely accurate statement since according to the following thread on Answers.com electrons don’t actually flow (or move) through a circuit at all: www.answers.com/Q/Why_is_electron_flow_in_the_opposite_direction_of_current.
@@chanrasjid8688 The video makes it clear that he is talking about "conventional" current.
@@Jim-mn7yq Stupid cations takin' all the credit for electrons' work.
Positrons?? Or Protons.
Positrons are Anti - particles of Electrons, It have same mass as of Electron but posses opposite charge.
You can use the term "electron" when talking about real flow, but when using conventional current terms is better to simply use the word "charge". So charges flow from + to -.
Wow! Finally, I get to understand why I don't see the line connecting back to the negative side of the power supply. I was really confused. Thank you very much for explaining it. I am currently studying a basic electronics course on UDEMY, but instructor did not explain this.
After many time at last i have understood that. THANKS
Absolutely phenomenal!!
Subscribed!!
Brilliant analogy thanks.you made it look so simple
That’s great information! Glad to know that ground symbols are essentially saying they’re returning to the negative side of the power source without causing clutter.
ruclips.net/video/upaVO_SMAQM/видео.html🙏👍
2:20 Current flows from +ve to -ve, whereas electron flow from -ve to +ve.
Why I love your videos ? I learn more and am less confused . I want to understand , to a novice it is a challenge.
Thank, you very much ;
it's really the most great channel i have ever seen in my life @
very good and useful explanation. Thanks.
Useful. Good stuff, mate.
Best explanation.
Thank you very much for the video.
Great job man! I have just started to learn about electricity at school an about the important laws. I think that your channel will teach me many things.
One question
What is the name of the programme you use for this animations?
Great video in reference to conventional electron flow
thanks so much, you r the best generous giver and aaa understabadle, I appreciate you true honest explanation.
Crystal clear explanation!
WOW your videos are awesome!! love this channel 😉😃😃
Excellent video
Hats off to you..
Now electronics seems much more simple
as usual no-one can explain these things completely and clearly, one must watch dozens of videos and put the info together to really see... this video comes closest than any other I have watched.
Informative video, thanks! Would love one on electric guitars.
ruclips.net/video/upaVO_SMAQM/видео.html 🙏👍
I have two questions. Why on this schematic the electrons flow from + to - and in previous videos it is shown exactly the opposite? For example in "How Batteries Work - Electronics Basics 2". Why do you put ground symbol in completely closed circuits in all previous videos?
Exactly what I was looking for.
It finally makes sense, thanks!
actually all the ground points are connected together in a pcb board, is that right?
Sir, the video was indeed helpful . Thank you😊. Can you please tell the name of the application you used for designing the circuit as I need it for my college project.
Thank you!
This video has saved the lives of countless half finished projects in The Box of Shame....
Thanks for this!
nice video, well explained. tnx m8
Very well explained. Finally I found a tutorial the clear this out for me. What is that software that you are using? It looks handy to draw circuits schematics.
Holy Shit thank you! I couldn't make any sense of this ground stuff before :)
I understand that the earth (i.e. ground) can serve as an infinite supply from which a circuit may draw electrons or an infinite sink into which a circuit may dump electrons. But, does ground when used as a practical (as opposed to theoretical) component within an actual circuit implementation possess a lesser (or greater) resistance / impedance to the flow of electrical current?
Thank you very much. Subbed.
Nice explanation for us laymen!
Thank you very much! Finally i understand what ground means!
+Vectro15 I'm very glad I could enlighten you :)
thanks for explaining. , please someone tell me the name of that program used to make circuit ? that guy used in the video.
thanks.
I second this
Everycircuit
best explanation. thank u
What program do you use for your schematics? I really want to be able to mess around with it.
Just saw it in his (another) video description - EveryCircuit. :)
Can i know the apps you used in connection of electronincs symbol?how to download it.thanks a lot
Liked, where do you get schematics for TV or electronics ?
TV? I am an industrial automation electronics engineer. If I need schematics, they generally include internal schematics of specific components such as ICs and many kinds of modules. Google is usually all I need. Sorry I couldnt help.
Thank you Sr.
So when drawing a schematic consider conventional current flow so you can ground the negative side instead of drawing loads of lines? In circuitry ground only exists purely for schematic purposes? In reality the only grounding would be on screened cabling to dissipate electrical noise?
Very informative video. What is the chassis ground please.
Great video! Which application are you using to simulate the circuit?
did you find the answer?
What about just an horizontal bar as ground symbol?
This is what i think is used outside the US.
I am not sure if you say electrons go to ground, as they are negative, thus beeing repelled. Did you mean charge instead?
Anyway good videos!
Hey,
May u explain more about Chassis Ground what is the usage and what is the difference between it and earth ground ?.
Thank u
Thank you for this informative video. Would you share the computer simulation you use to place components and simulate current flow in a circuit?
Its EveryCircuit @xtek
hi. I find this very confusing because on other videos i see illustrations showing electricity flowing from the negative to the + For example on a AA battery the the electric flows from the - side to the + side. however on this video at time 2:17 it is stating that electricity flows from + to - Please help explain this? on this video it states that electricity flows from - to + /watch?v=2BafNGDnxZw
hyylo This video is wrong. Electrons flow from negative to positive, but current flows from positive to negative.
very effective . thanku
Thank you. Now i get it
What software is this? Great video!
do bridge rectifier negative side must be insulated from earth ground? because in schematic it will short one of the diode because transformer connected to ground too?
Which circuit schematic software are you using? Any recommendations for Mac users.?
Hi can you link me to the program you use to simulate these circuits please ( love the channel btw)
Ha! Once again..learned something new. I had no idea you could add multiple ground points in every circuit. I have been adding them as you first demonstrated, with them all connected. Thanks!
You're Welcome :)
Thank,May I ask what is the program you're using ?
Hak MengHeang, the program's called EveryCircuit. It comes with a trial, that won't let you make more than a five element circuit at first, then expires and asks for $14.99.
what schematic editor did you use in the video?
Hello Sir, I am your new Subscriber.
And I have a question, Where did you get that circuit simulator??
Ty
I always wanted to ask this to my electrotechnic teacher about how could the current go to the ground, from the moment that we need a closed circuit in oder to have current to pass.
Because as we know (in theory), without closed circuit there is no possibility for current to circulate.
So that´s why whenever the current goes to the ground, we still have a ´closed circuit´.
Right?
Hi, there is something is not yet clear to me, if the electron flow is from negative to positive... what exactly and how exactly goes to ground? Thank
What electronics visualisation software do you use?
Amazing 👍👌👌
Your work is fantastic. I enjoyed learning with you. Could you make real simple circuits with various applications? For the sake of learning.
Could you please explain how capacitors store charge? and how it blocks charge in DC supply and not AC?
This is the highest amount of likes I’ve ever seen on one of your videos. (And it’s a really low amount).
Incase anyone didn’t get it, this is a compliment.
Exactly what I needed to know! Thanks man! Just starting with electronics and your channel will be much of a help :)
You are most welcome :)
thanks alot .. what program do you using?
You can use Proteus software. Maybe it's too late in order to respond to you 😁
what software is this? It looks fabulous.
Can you explaib a Circuit With Positive, Negative and Ground Connections. I read about split power supply and am confused
In the thumbnail the most remembered for me is the 1st one easily... because it's so basic and also fancy
What is the name of the software you are using to draw the electronic circuit?
hello, i'd like to know what software are you using? :)
EveryCircuit. You can use it online here: everycircuit.com/app/.
what platform do you use to simulate the circuit?
is it the same when we say the terminal is connected to earth or is earthed even though there is no such earth where it needs to get connected like house hold wirings.
Hey, what software are you using for the simulation?
What is that tool you used to simulate your circuit?
Just to be clear, ban you please elaborate a little on the flow of electrons. My understanding what actually flows from positive to negative is hole flow, am I correct?
Very nice, make a video about how Dc to Ac inverter works and how to increase the wattage, How squar wave, sine wave and pure sine wave works
hi. thank you. i wanted to ask if a person can get electrocuted if they simply stick there finger into the live/hot socket? or do does the person/human need to complete the connection by being connected to the earth.
You are always connected to earth with some resistance, so if you stick your finger in a socket, you will get shocked. Always ensure power is disconnected before working with any high voltages or AC Mains circuits.
hi. thank you for the reply. i want to ask a question about a 9-volt square shaped battery used in small devices around the home. if i put my finger on the negative side of a 9-volt battery and with the other hand i touch the soil in my garden will i get a electric shock? Will i get a shock if i used the same approach with a car battery?
Batteries work differently because they have no earth ground. The only ground for a battery is the negative terminal. I have a very detailed video about how batteries work. You will not get a shock from any single battery. Although if there are many batteries connected in series to bring the voltage high enough (50+ Volts), then you are at risk of shock and possible fatal injuries, but even then, this would only happen if you touched the positive and negative side of the series battery array. Earth Ground would not be involved.
Excelent!
What software is he using? That looks AMAZING!
Hi Dude! Please let me know if you know this software?
Every Circuit it's on Android qlso
Hi. I like your videos. I have a question. You said that electrons actually go from negative to positive. So If the negative is connected to the ground how can the electrons go through the circuit?
this is because the convention is that current flows from positive pole to the negative pole (and respectively to the ground which also 0 V, just like the negative pole). Scientifically although, the electrons flow from the negative pole to the positive pole. Thus the explanation he gives in the video is not entirely correct, because the electrons don't flow to the ground, but the current flows to the ground. The electrons are actually flowing from ground to the positive pole. However, while using a battery, there is no physical ground, because the circuit isn't connected to earth. As consequence the negative pole of the battery is considered as ground. The reason why there always is a ground symbol in his circuits is because the software EveryCircuit requires you to add a ground no matter what voltage source you use.
In a DC circuit the "ground" is not a connection to physical earth (PE) but rather a "common" point of reference for measuring voltage. Ground/Common/0V are more often than not used interchangeably. I prefer 0V.
The electrons actually go in the opposite direction to the current
Then what is "current"? Isn't current the flow of electrons themselves? That seems to upend this whole discussion. It's very frustrating to people trying to learn when these inconsistencies are thrown about like it doesn't matter. It does.
Richard Forester Current is the flow of electricity. Electrical flow is opposite to electron flow. Think of electricity as tension moving backwards from a locomotive to the wagons and electrons as the wagons themselves. The tension moves much faster than the train. Similarly, electrons move slower than crawling, whereas current moves at the speed of light.
Conventional current goes from positive to negative, but the electrons are on the negative side and travel to the positive side. You can think of conventional current as positive charges travelling to the negative side. Electrons travelling to the negative side doesn't make any sense, as negative charges repel each other.
what is the software used to make this cirucuits??
clear as air thx
4:26 alright so let me see if i got this right. All the loads are connected to ground, and the negative terminal is connected to ground. Electrons flow from positive straight to the ground, and *then back* to the negative terminal of the battery through the ground. The ground completes the circuit so the GROUND is supplying electrons to the battery as shown in the video
What app are you using for the circuit demonstration?
