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.
