other than just series or just parallel

Find: everything!

the equivalent capacitance Ceq

the charge Q on each capacitor

the voltage across each capacitor

the energy stored in each capacitor

the energy stored in Ceq

This circuit is a combination of parallel and series parts. We must reduce it in steps.

Now we will work back to our original circuit diagram to answer all of our questions.

The charge on each of these capacitors must be the same,

Now we are ready to replace the equivalent capacitor Ceq with the two original, individual capacitors C1 and C2;

Numerical Example: Parallel
