A 100 μF capacitor wired in a simple series RC circuit is initially charged to 10 μC and then discharged through a 10 k Ω resistor.
a) what is the time constant of the circuit?
b) what is the intial current that flows?
c) how much charge is left on the capacitor after 1 time constant?
d) what is the current after 1 time constant?
e) how much charge is left on the capacitor after 3 time constants have elapsed and what current is flowing then?
