Question

What is an example of a capacitance practice problem?

Answer 1

A camera flash is a practice problem.

Explanation:

In a camera, its flash has a 200`mu`F capacitor charged with 250Volts.

What is the energy stored in the capacitor?

`E=(C.V^2)/2`

`E=((200xx10^-6).250^2)/2` = 6.25 Joules
