Problem
A battery of emf E is connected to resistor R1 in series with a branch that contains resistor R2 in parallel with an initially uncharged capacitor C. The switch is closed at t=0. Which statement correctly describes the current through R2?
(a) It is non-zero at t=0 but becomes zero after a long time.
(b) It is zero at all times because the capacitor completely bypasses R2.
(c) It is zero at t=0 but becomes non-zero after a long time.
(d) It is non-zero at all times, decreasing from an initial maximum to a smaller steady value.
