Q6. A capacitor of 500µF is charged from a 24 V d.c. supply via a 200 Ω resistor. When fully charged, it is disconnected from the power supply and connected across a 20Ω resistor in order to be discharged. Calculate EACH of the following:

a) the peak charging current;  (2)

(b) the time for the capacitor to become fully charged;  (2)

(c) the time taken for the capacitor to charge to 12 V;  (3)

(d) the voltage across the capacitor after 25 ms of charging;  (3)

(e) the peak discharge current;  (2)

(f) the discharge current after 5 ms;  (2)

(g) the voltage across the capacitor after 5 ms of discharge.  (2)
