3. A 115-uF capacitor whose initial charge is 3.91 x 10-2 coulomb

3. A 115-uF capacitor whose initial charge is 3.91 x 10-2 coulomb is placed in series with a 2000-2 resistor and a switch, as shown. When the switch is closed, the capacitor begins to discharge. (a) What is the time constant for the circuit in seconds? (b) What is the current through the circuit when 1 = 2.0RC and when t = 4.0RC? 115 pF 3 2000
