Question

Which expressions give the energy stored in series and parallel combinations, respectively?

Options

• \[\frac{1}{2}C_PV^2\] and \[\frac{1}{2}C_SV^2\]

• \[\frac{1}{2}C_SV\] and \[\frac{1}{2}C_PV\]

• \[\frac{1}{2}C_SV^2\] and \[\frac{1}{2}C_PV^2\]

• \[C_SV\] and \[C_PV\]

Answer 1

The comparison gives the stored energy as one-half the equivalent capacitance multiplied by the square of the voltage. Use \[C_S\] for a series combination and \[C_P\] for a parallel combination.
