Awesome! Thanks @berkeman and @Greg (which greg? there are two)

@berkeman thanks for letting me know. I won't be using the other account. I intend to continue using this one from here on.

Hi all! Used to use this site a lot, so glad to be back.

I was reading Michael Faraday's story, and it described him using amber, wool, and small pieces of paper to bring about an amber-paper attraction. I tried doing this using the rosin from my violin case, wool-like material I found in my parent's room, and cutting up pieces of paper (very finely)...

Anyhow, using the heat you can now calculate the power (J/s). See that the heat is the 'J' and the time you have the 's'. Now think about how you can get current!

I think the asker had the converted number already [emoji846]. They wrote 151 kg.

I see. Thanks for pointing me in the right direction to understanding this!

I understand from my classes that, when looking to calculate the electric field of a charge we can use the electric field measured in its rest frame to find its electric field in the lab frame (where the charge is moving). The gamma factor changes the value for the component electric field if it...

Thank you all again!

Thanks for the critical comments. I will take it to heart. Thanks for spending your time reading.

Just one thought...which area of physics might be suggested as crucial? I have done only smatterings of classical mechanics and optics, and half-semesters of thermal physics, quantum physics, electromagnetism, and special relativity. Should my choice be merely based on my interests?

Thanks for putting out your opinions straight up like that...I will see to it that I get started right away (knowing full well that this holiday ain't enough).

Hi all! Now I don't know whether the question I am about to pose is something that can be answered intelligibly. Maybe it is just a case about motivation...but I am not too sure at the moment. My question is: Does mediocre performance in first and second year physics present a possible...

Thanks so much for the replies jbriggs444 and cnh1995! I still don't understand this fully, but I now know what is lacking in my understanding...thanks again!

Now, this is probably a very noob kind of question, but I am just going to say I just don't know how to answer this following series of questions. If we have a circuit, with a battery and bulb and the wires connected per normal, how do we physically explain the expenditure of energy in terms of...
