Excellent video by Joe. Couldn't explain it any better and simple then what he did. Great teaching and long may it continue. Thanks Joe top man and keep the great video's coming. Big fan 👍👍👍
I always thought that the Watt was defined as one joule of energy expended in one second. You say the joule is one Watt per second. Does it make any difference? I'm now confused.
Thank you very much for the channel and video! I started watching it in order to improve my English (I'm new to this), but I also get new and interesting information for myself. I have a question. What is the attitude in UK-electrics to welding and soldering wires? Are these connection methods recommended in the guidance documents, are they used in practice, and if used, how often? I would be grateful for your answer)
Thanks Joe. I think you've made a slight slip in your description. At 7.43 you say "3000 watts times by 60 for every minute that it's on" . You then multiply that by 60 again to get the hour figure. Surely it should be 3000 times 60 for every second that it's on then 60 to get to the Kw hour figure? Am I wrong?
Hmm, not sure @grumpygrampa, I think it's right as multiplying the power by 60 will give you a Watt minute effectively. Hopefully the message got across and it's just a matter of semantics.
hey Joe, is there a chance you could perhaps do a video on potential difference? in particular the relationship between energy, voltage and charge. The way you explain other subjects has helped me a lot so far and i don't quite understand where the 1V = 1JC(with this part being a reciprocal) when the formula i've studied is V= E (shouldn't this be W?) / Q. Thanks again for the videos 👍

Oh wow, thank you so much. I'm glad they're helpful. 😊
That was so easy on my brain. Thanks Joe
Great job! Thanks Joe
Thank you very much, you’re really good at simplifying those complicated stuff.
Just want to say thank you very much for these videos Joe helping out massively with my studies take care top man👍🏻👍🏻
My absolute pleasure, that's what they're here for! Glad they're helping. 😊
Excellent 👏👏👏👍
Really helpful, thank you!
Cheers joe. I don't have a worksheet but i might have to get one now. 😉
😀 Thanks very much, just click the link for a worksheet!
In the mechanical world, energy can be expressed in Nm. (Force times distance), 1 Nm being 1 J. Not to be mixed up with torque.
Absolutely, we'll cover that in a future video. 👍

You're welcome!

Joule is a derived SI unit. In base SI units, energy is measured in (kg×m^2)/s^2
