## Homework Statement

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).

## Homework Equations

## 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.
