Finding the Energy in a Capacitor and Inductor

7. What is the energy in joules stored in the capacitor below?
The capacitor is shown with 10 volts on each side of it (plus on the left of the capacitor, - on the right), and C = 20 microfarads.

8. What is the energy in joules stored in the inductor shown below?
There is a drawing of an inductor with 7 A flowing to the right, and below is written 7 m H.

Solution Preview

The energy U stored in a capacitor with capacitance C under potential drop V is given by:

U = 1/2 * C * V^2

In our case:

V =10v
C ...
