Homework Statement
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?
Homework Equations
I = Q / t
V = I * R
P = V * I
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.
