4. The circuit contains four parallel plate capacitors, all initially uncharged and with no dielectric material between their plates. A switch is closed to complete the circuit at time t=0, so current begins to flow at that time and we wait enough time for the capacitors to become (very close to) fully charged.
a. What is the equivalent capacitance of this circuit?
b. What is the charge stored on the 125 µF capacitor?
If we now insert a neoprene rubber dielectric into all of the capacitors, how will the answers change?
c. What is the equivalent capacitance of this circuit?
d. What is the charge stored on the 125 µF capacitor?
When the switch is closed in the figure below, the capacitor charges
with a characteristic time constant 71. On the other hand, when the
capacitor is fully charged and the switch is opened, the capacitor
discharges with a characteristic time constant T2. What is the ratio T1/T2?

R2
A. R/(R + R)
B. (R2 + R2)/R1
C. R1/(R + R2)
D. (R1/R2)(1+ R1/R2)
E. 1
The switch in the circuit has been in position a for a long time, so the capacitor is
fully charged. The switch is changed to position b at t = 0.
a. What is the current in the circuit immediately after the switch is changed to b?
b. What is the current in the circuit 25 us later?
C.
What is the charge Q on the capacitor 25 µs later?
