I have a question sir. At 1:07 you say the number says how much KW the heater needs per second to be working. At 3:00 you calculate it with 3 x 2Kw, but if it is by second wouldnt it need to be calcualted totaly diferent?
@@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?
@@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 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!
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.
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.
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.
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
@@jacoblehman8714 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.
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.
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.
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
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 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.

Not 30sec/hr.

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 ??
This should be on every power company website
Good job.
Small mistake at 3:33. Don't convert time from 30s/hr but only from 30s.
You so good
