The time for the capacitor voltage to fall to 20 v, Electrical Engineering

Assignment Help:

A capacitor is charged to 100 V and then discharged by a 50 kΩ resistor. If the time constant of the circuit is 0.8 s, verify:

(a)  The value of the capacitor,

(b)  The time for the capacitor voltage to fall to 20 v,

(c)  The current flowing when the capacitor has been discharging for 0.5 s

(d)  The voltage drop across the resistor when the capacitor has been discharging for one second.
