Lecture 22, ACT 1

• At t=0, the switches in circuits I and II are closed and the capacitors start to charge.

  • What must be the relation between eI and eII such that the current in the circuits are the same at all times?

• Suppose at time t, the currents flowing into C and 2C are identical and that 2C has twice the area of C as shown. Compare the magnetic fields at the points shown BI(ro/2) and BII(ro/2):
