@@HumbleThyself230 They there, thank you for taking the time to read my comment but I am still confused. At 1:06 he says the 2000 wats is the "energy demand per second". So wouldnt that mean you would need to calculate 2000 x 60 x 60 to get a KWh isntead of the calculation at 3:00?
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 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".

In the beginning of the video you state the Watt rating on the box/package indicates how much power is used per second. If a 60W light bulb is used for one hour, that would be 60W per second at 60 seconds per minute at 60 minutes (60W x 60 x 60) for a total of 216,000W or 216kW. 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
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.
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.

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"?

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.
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

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.
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.

No. A lamp rated at 60 W means it's active power (a.k.a. real power) is 60 W. This means the average of the instantaneous power in steady-state is 60 W, or in other words it means the average rate of flow of energy is 60 joules each *second* (not hour).
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.
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.

Dude you're over complicating it. Cant you just use (watts of device)/(1000 for the kw) then multiply that by your price per kWh. That gives you the price per hour for the device. You can then multiply that answer times a percent of an hour if needed
Hola 👋hay una parte que no entiendo si es watt × segundo en caso de bombillo de 100w y se multiplica por hora por ejemplo 4 h. , porque ? Si 100w es en un segundo no en una hora para que se multiplique por 4 🤔🤔🤔🤔

So, if a generator says its output is 1948kwhr than what will be its power actually?? And if i want to calculate its actual output for one hour how will i do it?
It would be more or less determined by what you connect to the generator. A 60W lamp would draw 60W*h where h is how many hours your lamp is on. If no apparatus is connected to the generator no energy would be drawn from it.
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.

In the beginning of the video you state the Watt rating on the box/package indicates how much power is used per second. If a 60W light bulb is used for one hour, that would be 60W per second at 60 seconds per minute at 60 minutes (60W x 60 x 60) for a total of 216,000W or 216kW. So is the statement at the beginning of the video accurate? If so, what am I missing?
60w bulb will consume 0.06 kwh per hour or 0.6 kwh for 10 hours
Energy is measured in kWh ,so you need to convert watt in kilowatts and seconds in hour to get the energy ,60 W is 0.06 kW and 60 minutes is 1hour
@@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?

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.
@ he said that
Nvm i realize what you ment
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.
As per wht he said 60w is per second .then per hour 60x 3600 will get per hour and then times 10 will be the correct answer 😂
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

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"?

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.
Nice video... Cool editing.... What program do you edit with.
I just pay the electrical bill and call it good. But nice to break it down if I need too, haha.

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

please explian the convert 750 squad
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.

so when it says a 60W lamp, it is not per second but per hour 60W x 10h = 600Wh =0,6KWh
No. A lamp rated at 60 W means it's active power (a.k.a. real power) is 60 W. This means the average of the instantaneous power in steady-state is 60 W, or in other words it means the average rate of flow of energy is 60 joules each *second* (not hour).
@@altuber99_athlete yeah, then convert it to kilowatts. and rate it to 1 hour. still 60w. wtf
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.
Why 30 seconds?
@@LFOVCF because you are working out kWH not KWS
You can, but you'll get 60 kWs (Kilo-watt-seconds). If you convert it by dividing by 3600, you'll get 0.016 kWh, which is basically the same.
@@jeremykemp3782 So you're saying that for a device that uses 100Watts they mean by that 100W/h ??

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.
Thank you. My brain was going to explode or shortcut with 1000kW=1W 💥💀....

Dude you're over complicating it. Cant you just use
(watts of device)/(1000 for the kw) then multiply that by your price per kWh. That gives you the price per hour for the device. You can then multiply that answer times a percent of an hour if needed

Perhaps you could have just said that "k" means kilo means 1000
So we could better understand that conversion easily like 1w×1000=1kw..

Hello teacher
please how to calculate hammer drill ? you know the power is variable
So, if a generator says its output is 1948kwhr than what will be its power actually??
And if i want to calculate its actual output for one hour how will i do it?
It would be more or less determined by what you connect to the generator. A 60W lamp would draw 60W*h where h is how many hours your lamp is on. If no apparatus is connected to the generator no energy would be drawn from it.
