A 10 pF capacitor is connected in series with a 100 kilo-ohm resistor across a 100 V DC supply. Calculate: (a) the time constant; (b) the initial charging current; (c) the time taken for the p.d. across the capacitor to grow to 63V; (d) the current and the p.d. across the capacitor 3.0 s after it is connected to the supply; (e) Compare the value obtained in (c) with the time constant of the circuit. What does it tell you about estimating a circuit's time constant?

You find that a 25-F capacitor connected to 480 VAC is defective. The storeroom has no capacitors with a 480-VAC rating. However, you find two capacitors rated at 50 F and 370 VAC. Can these two capacitors be connected in such a manner that they can replace the defective capacitor? If yes, explain how they are connected and why the capacitors will not be damaged by the lower voltage rating. If no, explain why they cannot be used without damaging the capacitor.
