Solution: In the circuit show in the sketch the battery emf is ε = 48.0 V, R = 8.0 Ω, and C = 4.0 x 10-6 F. Initially the switch is open and the charge on the capacitor is zero. At time l after the switch is cl

Problem

In the circuit show in the sketch the battery emf is ε = 48.0 V, R = 8.0 Ω, and C = 4.0 x 10-6 F. Initially the switch is open and the charge on the capacitor is zero. At time l after the switch is closed, the current in the resistor is 2.00 A. When the current has this value, what is the charge q on the capacitor?

A) zero

B) 64.0 x 10-6 C

C) 128 x 10-6 C

D) 192 x 10-6 C

E) None of the above answers
