A circuit contains a single 250-pF capacitor hooked across a battery. It is

desired to store three times as much energy in a combination of two capacitors

by adding a single capacitor to this one. How would you hook it up, and what

would its value be?

Answer:

a 500 pF capacitor connected in parallel will triple the energy storage
