Switch "S" is closed at time t = 0 sec. The capacitor is initially uncharged. Take R1 = 5 Ģ; R2 = 200 Ģ; C = 10 ĢF; V = 6 volts.
(a) Find the current through each resistor a short instant after the switch is closed.
(b) After the switch has remained closed for a very long time, how much charge is on the capacitor and which plate holds positive charge?
(c) The switch is now reopened. How much charge is on the capacitor 500 Ģsec later?
(d) Sketch a graph of the current through R1 after the switch was reopened (in part c).
