Question

The energy stored in a condenser is in the form of

• A. electrostatic energy
• B. magnetic energy
• C. elastic energy
• D. kinetic energy

Answer 1

The correct option is A electrostatic energy

Energy in a condenser is always stored in the form of electrostatic energy ($U$) and it is given by
$U=\frac{1}{2}\frac{Q^2}{C}$
where $Q$ is the total charge and $C$ is the capacitance of the condenser.
