Question
A 5.0 F capacitor is charged to 12 V and placed in the RC circuit shown. At time t = 0 s, the
switch is closed, allowing the capacitor to discharge into the 400 Q resistor.
a. What is the time constant (in seconds) for this RC circuit?
b. After how many time constants is the charge on the capacitor one-fourth of its initial
value?
