A 20µF capacitor is connected in series with a 50 kΩ resistor and the circuit is connected to a 20 V, d.c. supply. Verify:
a) The initial value of the current flowing,
b) The time constant of the circuit,
c) The value of the current one second after connection,
d) The value of the capacitor voltage two seconds after connection,
e) The time after connection when the resistor voltage is 15 v
