Q2. A 600  capacitor is charged from a 30 V d.c. supply via a 250 Ω resistor. When fully charged the capacitor is disconnected from the supply and connected across a 25 Ω resistor in order to be discharged. Calculate EACH of the following:

(a) The initial charging current; (2)

(b)The capacitor voltage after 137 ms; (4)

(c) The time taken for the capacitor to charge to 22 V; (3)

(d)The initial discharge current; (2)

(e)The discharge current after 30 ms; (3)

(f)The resistor voltage after 30 ms of discharge. (2)
