@ceooflonelinessinc.267 at 1:07 he is saying KW is the energy demand measured in Joules per second, which is Watts. To get KWh, we multiply the energy usage of the item(KW) by the amount of hours it runs to get the output of KWh. Does that make sense?
As a 15year old girl, I'm just curious to know how electricity bills are calculated so I can be aware of money finicially and not interested into engineering. The video is understandable, thank you!❤❤
I am sure many folks are wondering why electricity seems so cheap in your example. 10 cents a kWh is pretty cheap but if that is what you pay realize in the US anyway, most utility companies tack on all kinds of extra charges (many required by the government and some as a means of passing on other costs). Distribution, transmission (yes, two different things) low income supplement charge etc, etc. By the time you are done, kWh goes up since many are based on your kWh some are flat rate. Expect to see 30 to 35 cents per kWh or where I live a lot more. You did a great job, thank you.
I love your videos brother, # 1 video wen it comes to engineering mind set like the title says. Every time I find your video I feel like I have seen a movie I waited for long.
Thanks for all these videos! College physics was decades ago, and going long periods of time not doing any electrical work, these are all great reviews. Of course for ths real stuff, I hire a licensed electrician. So great to study this again, wish your videos were around when I'd be burning the midnight oil studying. Cheers!
Some comments on your discussion on units. Unit analysis is key to understanding in these calculations. The definition of a Joule as energy is not wrong but it is vague and barely mentioned and many would miss the important point that a Joule is a unit of work (defined as force x distance). It should be stressed that you are paying for work. The work it took to move the electrons (current) down the wire. Power (measured in Watts is the rate of doing work (power=work/time), where the units 1Watt=1Joule/sec. Or more simply the force (volts = Joules/Coulomb) to move a bunch of electrons (Coulomb = 6.24 x 10e18 electrons ) down the wire on a per second basis (1Ampere=1C/s). Where, Watt = volts x amps Or. Watt = Joules/C x C/s Watt = Joules/s The rate of doing work Hence since a Wh = work/time x time, time cancels and work is left, measured in 1000s = Kilo (K) or KWh. One final note. At 3:19 there is a minor oversight in the units of the bottom equation. It should read; 30sec ÷ 3600sec/hr = 0.0.0083hr Not 30sec/hr. All in all a good presentation.
I appreciate HIGHLY That it is explained what a watt is. That the origin/meaning is just the name of the eventor. And not some other meaning that would need further work in discovering.
Wait, at 0:56 he says "On the electrical goods you purchase, you'll see a value stated in W or kW; This is the power demand of the item, it tells us how much energy _per second_ this will demand to work." So according to that, a 100W lightbulb should require 360kW per hour (100W x 60 seconds x 60 minutes = 360,000W or 360kW). This is obviously wrong, but where is the error? Did he misspeak and mean to say "per hour" instead of "per second"?
2:25 Why can't I take 2kW and multiply it with 30 seconds? You explained that the kW values stands for the energy used in one second. Thanks for this great video!
You can. Hours are used for much higher amounts for daily use. Any unit of power multiplied by a unit of time will give you energy. You have to be careful with the units, though.
In the first, he explains how much energy is in one kw (measured in joules/s) In the second, he explains how much of that energy constantly being used by that machine for the period of an hour (kwh * number oh hours * number of days = total wattage used that month)

It's not per second it's per hour. If you have a 2kW heater it will consume 48kW per day.
Diana J it means the rating on the devices are per hour and not per second. If the heater is 2kW, then it’s per hour consumption rating. If heater runs for 2 hours a day a month (30 days), then it will be taking 2x2x30= 120kWh from your energy bill.
This is really practical, I rally enjoyed the video. Please explain more on power factor surcharge on electricity billing and how can one fix the surcharge issues on bills.
Sir ,u r awesome. My sincere thanks and gratitude goes to u for putting tremendous effort and hours to explain engineering stuff to us. Could u please make a series of videos that shows in steps how to design an HVAC ,plumbing and fire fighting system for a project u have worked on ? Nowadays it is harder to land a job in the engineering sector as a fresh graduate. Plz that will make a huge impact in my life if u could give series of training videos on how to design engineering systems such i mentioned above. Many thanks to u again
at around 2:15 you've got some terms back to front. 1 Kilowatt or KW = 1000 watts, not 1w=1000kw. Otherwise great. Actually, if you swap your operators it would be fine. swap your division for multiplication.
I understand the confusion now. I have said at 2:06 "1kW x 1,000 = 1,000 Watts" I am literally typing "1 x 1,000" in the calculator to get the 1,000W answer. But you have interpreted that as me saying type "1,000 x 1,000" which would give 1,000,000W. I use the kW value as is, I don't replace the K with zeros. E.g. if it was 15.8kW I would type "15.8 x 1,000" into the calculator, not 15,800 x 1,000". I thought it was clear in the video but many people have had this problem so when I remake the video I will explain this more clearly. Thank you for the feedback, appreciated.
So, since 1 kW is 1000 J/s, why don't we have to convert a kW into a unit per hours before calculating how many kWh are used? In the beginning of the video you mentioned a multiplier of x3600 for seconds in an hour, but then it was never used
Not sure to understand but kWh is already a unit showing how much energy is used/spent in one hour. No need to recalculate anything in hours then, already done. If I got your question.
At point 2:04 I think there's an error, it should be: kW/1000 = W or kW = 1000 W or kW = W x 1000. Tip: think of k = 1000 and when you see (kW) it's basically (1000 W)
That's what I thought, but when you say that 1 kw x 1000 is the same as 1000 watts, his explanation makes sense. This is one of those examples where the cracks in the logic of math show

So is the statement at the beginning of the video accurate? If so, what am I missing?
@@mar-tin702 So the statement that the watt rating on the product box indicates the power used *per second* is false. A 60W rated product actually uses 0.01666666W per second?
@@DanThemes you know how much energy a lamp would consume if it was 60w per second?? Energy is power in kilowatt x time= (kWh) 60 W is 0.06 kW since 1kW is =1000 W so a bulb of 60 W will consume 0.06 kW x 1 hour= 0.06 kWh in 1 hour
I was missing the most important part of information regarding the Kwh, how much work 1 Kwh is. If someone would take a back pack and load it with some drinking water, (he will probably need it) so that he all together weighs 100 kg. How many stairs does he need to climb before he has made the work of 1 Kwh? When you know that, you can start to have an idea about what a Kwh is.

Thank you so much for the videos! I really enjoy watching them a lot. But I have a question on this video. I don't know why "KW * 1000 = W"(2:15).Because earlier you said, 1 W = 1 joule, and 1 KW = 1000 joules.Therefore, Is it possible that you meant to say W * 1000 = KW?
1 Watt = 1 Joule Per Second (J/s) 1 kWh = 1000 Watts Since 1 Watt is 1 Joule/s & there's 3600 seconds in an hour, 1 Watt Hour is 3600 Joules. Then, a kWh is 1000 Watts & again, there's 3600 seconds in an hour, that's 3,600,000 (3600*1000) Joules in a kWh. Yes, I'm pretty sure you're correct on your last statement there. Think about it as the metric system. 1 Meter * 1000 = 1 Kilometer. Same with the electrical power, 1 Watt * 1000 = Kilowatt. Hope this helps!
@@sid9139 i was looking for that comment caus i do think he reversed those two. Cause theres no way a watt equals 1000 kwatts that's a 1 to a million ratio
No. Think of mass if you want. If tou have 1 Kg of sugar and you want the grames, you multiply by 1000. Because thats what the " K" means. Its a way to put 1000 shortly. Just like the "m" in miligrames mean (1/1000) .
@@Sole-. I see what you did there, but I still think that is incorrect. If 1 kW = 1000 W that must mean that if I multiply 1 kW by 1000 I would have 1,000,000 W. I think following the units will help in this case. He has an equation: 1 kW x 1,000 = 1,000 W. If you devide both sides by 1,000 you get 1 kW = 1 W, which we know to be false.
What does he read every day? What are his practice sessions like? How does he come up with this level of word play? How does he have instant access to knowledge in all areas? How often is he reading? Whats the split between knowledge and practice?

Great video Paul! A lot learnt mate. Keep the education flowing. Question: what about if you only have the unit cost per KWH and not KW.H? How o convert and confirm to pence.? I.e, £0.10p Kw.h. Your help is appreciated. Cheers
There is a common confusion between kWh and kW. KWH, kWh is the same as kW.h and it is a unit of energy. Note that the h is not under a fraction. It's kilowatt TIMES hour. Let's say the cost of energy is 16c/kWh. My kettle used 0.5kWh of energy to boil my water. It cost me 8c. Now it doesn't matter how long it took the kettle to boil it. Let's say you want to still measure its Power in kilowatts. It took 12 minutes for the kettle to boil that. This means 0.2 hours. The kettle used a power equal to Energy = 0.5kWh divided by Time = 0.2h. 0.5kWh/0.2h = 2.5kW
Many people, including myself, often mistake the kWh unit of measure for how many killowatts a device will use per hour, which is wrong. The easier way to think about this so as to get it right every time is to imagine how much energy a device will use in a TIME INTERVAL. This could be an hour, but it can also be a minute, a couple of hours, a week etc.

One final note.
At 3:19 there is a minor oversight in the units of the bottom equation.
It should read;

I was missing the most important part of information regarding the Kwh, how much work 1 Kwh is. If someone would take a back pack and load it with some drinking water, (he will probably need it) so that he all together weighs 100 kg. How many stairs does he need to climb before he has made the work of 1 Kwh?
When you know that, you can start to have an idea about what a Kwh is.
This is a Old Video, But @ 2:08 isn't stated correctly. 1 kilowatt is 1000 watts! I'm not sure what is calculations are there?
I understand the confusion now. I have said at 2:06 "1kW x 1,000 = 1,000 Watts" I am literally typing "1 x 1,000" in the calculator to get the 1,000W answer. But you have interpreted that as me saying type "1,000 x 1,000" which would give 1,000,000W. I use the kW value as is, I don't replace the K with zeros. E.g. if it was 15.8kW I would type "15.8 x 1,000" into the calculator, not 15,800 x 1,000". I thought it was clear in the video but many people have had this problem so when I remake the video I will explain this more clearly. Thank you for the feedback, appreciated.
This is the best explanation I've found! Thanks a lot!
I found the video very simple and easy to understand.
Thanks
Thank you so much this video is really helpful!
Nice video... Cool editing.... What program do you edit with.
Thank you for the awesome content! Very helpful
No not at all. So many flaws in this video.

Hey paul. You are the best.
Thank you so much for the videos! I really enjoy watching them a lot. But I have a question on this video. I don't know why "KW * 1000 = W"(2:15).Because earlier you said, 1 W = 1 joule, and 1 KW = 1000 joules.Therefore, Is it possible that you meant to say W * 1000 = KW?
1 Watt = 1 Joule Per Second (J/s)
1 kWh = 1000 Watts
Since 1 Watt is 1 Joule/s & there's 3600 seconds in an hour, 1 Watt Hour is 3600 Joules.
Then, a kWh is 1000 Watts & again, there's 3600 seconds in an hour, that's 3,600,000 (3600*1000) Joules in a kWh.
Yes, I'm pretty sure you're correct on your last statement there. Think about it as the metric system. 1 Meter * 1000 = 1 Kilometer.
Same with the electrical power, 1 Watt * 1000 = Kilowatt.
Hope this helps!
@@sid9139 i was looking for that comment caus i do think he reversed those two. Cause theres no way a watt equals 1000 kwatts that's a 1 to a million ratio
No. Think of mass if you want. If tou have 1 Kg of sugar and you want the grames, you multiply by 1000. Because thats what the " K" means. Its a way to put 1000 shortly. Just like the "m" in miligrames mean (1/1000) .
@@Sole-. I see what you did there, but I still think that is incorrect. If 1 kW = 1000 W that must mean that if I multiply 1 kW by 1000 I would have 1,000,000 W. I think following the units will help in this case. He has an equation: 1 kW x 1,000 = 1,000 W. If you devide both sides by 1,000 you get 1 kW = 1 W, which we know to be false.
@@dracophyle I have made a mistake in the video. This will be updated soon in a new version
Love all about physics!
Great, great video.
What does he read every day? What are his practice sessions like? How does he come up with this level of word play? How does he have instant access to knowledge in all areas? How often is he reading? Whats the split between knowledge and practice?
At 2:14 the conversation KW x 1,00=watts (W). Isn’t 1w x 1000=1kw. I’m confuse. Help.

Great video Paul! A lot learnt mate. Keep the education flowing. Question: what about if you only have the unit cost per KWH and not KW.H? How o convert and confirm to pence.? I.e, £0.10p Kw.h. Your help is appreciated. Cheers
There is a common confusion between kWh and kW.
KWH, kWh is the same as kW.h and it is a unit of energy. Note that the h is not under a fraction. It's kilowatt TIMES hour.
Let's say the cost of energy is 16c/kWh.
My kettle used 0.5kWh of energy to boil my water. It cost me 8c.
Now it doesn't matter how long it took the kettle to boil it.
Let's say you want to still measure its Power in kilowatts.
It took 12 minutes for the kettle to boil that. This means 0.2 hours.
The kettle used a power equal to Energy = 0.5kWh divided by Time = 0.2h.
0.5kWh/0.2h = 2.5kW
Thank you for educating me.
Very simple and clear explanation
Everyone should do physics at school, coz this stuff is valuable to know, but easy to work out
Zabardast video... Thanks dear...
Thank you for the video!
You made this so easy to understand thank you so much
No he didint
complete tutorial,nice
Can you please explain mAh (power bank capacity) in detail?
I have little confusion in that topic.
May you explain?
Please...
This does actually help.
I really needed this thanks
Please explain how the capacity of a battery is measured.
Check this out, how a battery works: ruclips.net/video/PXNKkcB0pI4/видео.html
Thank you so much. Just perfect
i am fully satisfied with your video.you are too good in basic knowledge...i like it dude
Thank you for the video it was really helpful with class!
At 1:48 how would you write that as an equation? Just wondering... thanks
Would it be this? 1amp * 1ohm / 1sec = 1 joule of heat
Great video!
Please discuss something about heat rate of a diesel engine power plant
Very good service
Many people, including myself, often mistake the kWh unit of measure for how many killowatts a device will use per hour, which is wrong. The easier way to think about this so as to get it right every time is to imagine how much energy a device will use in a TIME INTERVAL. This could be an hour, but it can also be a minute, a couple of hours, a week etc.

Great Video
Thank you for being a great teacher!
Actaully he a horrible teacher. So many flaws in this video it's insane.
Hi ..pls explain physical significance of nuetral and earth wire in home wiring.
@2:16 I'm pretty sure kW / 1000 = Watts and W x 1000 = 1 kW
How come nobody noticed this?
I noticed as soon I saw it.

Finally understood this
I wondered why my electric bill jumped so high? Damn you Heated Fan!
electric heater blower not heated fan
Yes but what would it take to generate the 1.21 gigawatts necessary to power the flux capacitor
This is cool. I'm glad to have electricity. I want to find out how much I'm spending on electricity each month. If I copy him and build a table. I may be able to find out how.
Please make a video on power and energy difference plz
