(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The course that I am taking is so poorly organized. I keep having to do questions (for marks) for which I haven't even studied the principles yet.

But anyway, I was hoping someone could help me with this, I assume basic, question about electric circuits. I studied electric circuits last year and I barely remember.

4.24 * 10^18 electrons pass through a wire between points A and B in 0.0025 s. In the process, 24 J of heat are given to the wire. What is the difference in potential between points A and B?

2. Relevant equations

I = Q / t

V = I * R

P = V * I

3. The attempt at a solution

I have calculated the current going through the wire to be

(4.24 * 10^18) * (1.60 * 10^-19) / 0.0025 = 271.36 A

What relationship between I and V from

V = I * R

P = V * I

can I use? What exactly does the 24 J represent?

Thank you for anyone who can help.
