FREE Expert Solution

In this problem, we'll combine capacitors in series and in parallel and determine the charge stored in a capacitor.

For capacitors in series, the equivalent capacitance is:

1Ceq=1C1+1C2+...+1Cn

or

For two capacitors:

Ceq=C1C2C1+C2

For capacitors in parallel, the equivalent capacitance is:

Ceq=C1+C2+...+Cn

The charge stored by a capacitor:

Q=CV
