A circuit has the following R = 10 k, C = 25 F, = 12 V.
How long will it take to charge the capacitor, C, to 10 V ?
How much current is flowing in the circuit at that time?
A circuit has the following R = 20 , C = 25 F, = 10 V.
How long will it take for the charge to drop to one third its original value?
