1. The problem statement, all variables and given/known data Check out the attached image. The electromagnetic field B is constant. The rod is moving through the rail and an inductive emf V is produced on the closed loop. Due to that, the condenser C has a voltage difference Vc. Question: Express the relation between the total emf produced V and the condenser's voltage difference Vc in function of C and the resistance r (check out the attached image). 2. Relevant equations 3. The attempt at a solution Well, no idea at all. I tried this: The total emf produced V = Vc + voltage of the resistance Vr As the condenser and the resistor are connected by conductors, they must have the same voltage, so Vc = Vr Then, I will get V= 2Vc. BUT, the question asks me to express the relation between V and Vc in function of C and r. What I got is a simple V=2Vc. Please help.
