Concept

Problem: You have two identical capacitors and an external potential source.Compare the total energy stored in the capacitors when they are connected to the applied potential in series and in parallel.U(parallel)/U(series) =?

FREE Expert Solution

Energy Stored in a capacitor:

U=12CV2

Equivalent capacitance in series:

1Ceq=1C1+1C2

Equivalent capacitance in parallel:

Ceq=C1+C2

Connecting two identical capacitors in series will halve the capacitance.
