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.
@@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.
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
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.
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.
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.
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!
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.
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. :)
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.
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 -.
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!
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.
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.
is electron really flow from (+) to (-) ? That's not what I've learned in school. Electron will travel from (-) to (+), and current direction is opposite to electron's direction.
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.
at 2:48 it looks like the negative side of the battery is connected to (earth) ground. Why is the circuit still closed and why does no charge go to (earth) ground ?
At [5:17] you say that electrons no longer carry charge. Electrons by definition carry a negative charge and always do for as long as they are electrons. Furthermore, the animation does not showing electrons; it shows "holes" of positive charge sinking into the Earth. The negative terminal of the power source attracts an equal number of holes from the Earth and for this reason we have an electrical circuit. The physical reality is of course the reverse, with electrons moving in the opposite direction to the "holes" of positive charge.
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.
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
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?
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.
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.
seethegalaxy electrons are pressurized, this creating voltage. Voltage flows through the conductors into loads or resisters and lose its energy, which is provided by the Voltage Source or power supply.
Picture firing a gun at a metal plate. The bullet comes out of the muzzle with a lot of speed. Now assume the bullet has just enough energy to pass through the plate, after which its velocity and so its kinetic energy drops to 0
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?
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!

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.
@@ellewharton7394 2:08 he specifically says "using Conventional Current..." which is terminology you will want to get familiarised with, if you haven't yet.
@@LeeValentine001 Not even in conventional current electrons travel to the negative side, as negatives repel each other. In conventional current positive charges travel to the negative side. You may want to familiarise yourself with conventional current before suggesting other people do.
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?
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.
Atoms are neutral because they consist of an equal number of positive (protons) and negative (electrons) particles but that is not the end of the description. In addition, the following are inherent in neutral atoms: The fields due to the protons and electrons always exist, penetrating everything, but they cancel each other so well that there is hardly a net electric field around the atom! When electrons are separated from nuclei of a stable neutral atom the strength of the electric field around the atom grows which disturbs 'neutrality'. A conductor or any substance made from neutral atoms we can say is neutral when there is no significant field surrounding it. All locations at infinity, in all directions from the substance, are at the same potential namely “zero" and maybe considered as a 'reference'. A neutral piece of wire with its millions and millions of neutral atoms is good enough to be labelled as a ‘reference’ and also as ‘0’ volts. It maybe called "circuit zero" or "ground" as is done in electric circuits. What is fascinating about an atom is how it remains “neutral” despite it being a collection of sources of powerful electric and magnetic fields. The electrons at very high speeds orbit the central core (in the classical view) so perfectly balanced that the “net” electric field is very close to zero outside the atom. Because of this astounding assembly of sub-atomic particles….for all time…..the e-field never becomes significantly non-zero even for the tiniest fraction of time…..the cancellation of the fields outside is ever so precise. If it were not so, we would be living in a “shocking” world ! and..... …you would be shocked by anything you touch ! But what happens if there is some excess charge deposited on the substance? It is charged and it has a potential. Since charge cannot be destroyed the only way we can make the potential of the substance nearly 'zero' is to connect the substance via a thin conducting wire to a large conductive sphere. The charge will then spread out over that large sphere and make the potential of the substance nearly zero. That conductive sphere maybe conveniently the earth! And thus emerged the idea of 'earthing'. When the charge migrates to the large sphere there is a current.We note we are observing phenomenon related to both electrostatics and circuits. Electrostatics and circuits belong to one science, not two. These are discussed usually separately in textbooks and science and engineering courses. For too long has circuit theory been confined to analysis using math and has been depriving practitioners of the richness in its physical aspects.

I'm a bit confused. When I was at school my physics teacher said electrons were negatively charged and flowed from the negative side of the battery to the positive. Now ur saying it's the other way round. Mind you my physics teacher was a bit thick so he probably had it wrong.
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?
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?
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.
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
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?
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.
so could i get an led and get a battery and hook up positive to the positive side then just stick the negative side into the ground via a wire or or attach it to something metal and it would light up?
AverageGeek so essentially it's just used as a reference where the electrons want to flow for concept reasons but it doesn't work that way in a real world application?
@@andromeda_yt_ There's more to it than that, as anyone who's blown up their oscilloscope can probably tell you. It's usually because they don't understand what earth references are!
Not only you can draw it! You can actually connect negative to a metallic chasis and connect all negatives to the chasis too. Electric circuits in cars had always been connected this way.

Can someone give me the name of the programme that he uses to create his circuits? and tell me if its free.
What's the simulator used in this video.
Excellent video
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
Could you say what is the software u are using
what software is this? It looks fabulous.
What is the name of the program used here?
Which circuit schematic software are you using? Any recommendations for Mac users.?
Thank, you very much ;
it's really the most great channel i have ever seen in my life @
What software is this? Great video!
He said conventionally current flows positive to negative and that is correct.
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?
What's the software you're using
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.
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
so could i get an led and get a battery and hook up positive to the positive side then just stick the negative side into the ground via a wire or or attach it to something metal and it would light up?
+NoVaKane No.
AverageGeek k didnt think so. Thank you
AverageGeek so essentially it's just used as a reference where the electrons want to flow for concept reasons but it doesn't work that way in a real world application?
It finally makes sense, thanks!
Which software do you use please tell.
Hey, what software are you using for the simulation?
Simply put, ground is bin for the waste to get dump. - ve terminal is the 4th name for ground.
I was expecting to hear more explanation on the other two ground symbols. You only explained one, basically.
@@andromeda_yt_ There's more to it than that, as anyone who's blown up their oscilloscope can probably tell you. It's usually because they don't understand what earth references are!
can you please tell me where i can download that software
hi what's the simulation program u use for ur circuits
i liked your channel
please tell me which software are you using
Everycircuit.com
what happens with the electrons when they stock up at the minus pole? they just fly off into the air?
farerse
No, the electrons will travel to the whole circuit again
Not only you can draw it! You can actually connect negative to a metallic chasis and connect all negatives to the chasis too. Electric circuits in cars had always been connected this way.
which app you used to explain this video?
