# Calculating the Potential Difference

Not what you're looking for?

Question: Consider a generator constructed as shown in the attachment. The loop in this generator rotates at an angular rate of w. The slip rings in this design ensure that the same leg of the rotating loop is always connected to the same output terminal. Show that the potential difference between the output terminals is given by E= E0 cos theta (where theta = wt is the angle that the plane of the loop makes with the magnetic field direction at time t), and determine E0 in terms of the loop's length L, width W, the magnetic field strength B, and the loop's angular rotation rate w.

##### Solution Summary
