Problem Details

A circuit is wired up as shown below. The capacitor is initially uncharged and switches S1 and S2 are initially open.


1) What is the voltage across the capacitor immediately after switch S1 is closed?

a) Vc = 0

b) Vc = V

c) Vc = 2V/3


2) What is the voltage across the capacitor after switch S1 has been closed for a very long time?

a) Vc = 0

b) Vc = V

c) Vc = 2V/3


3) After being closed a long time, switch 1 is opened and switch 2 is closed. What is the current through the right resistor immediately after switch 2 is closed?

a) IR = 0

b) IR = V/3R

c) IR = V/2R

d) IR = V/R


4) Now suppose both switches are closed. What is the voltage across the capacitor after a very long time?

a) Vc = 0

b) Vc = V

c) Vc = 2V/3
