For an lc circuit, when the charge on the capacitor is one-half of the maximum charge, the energy stored in the capacitor is?.



Answer :

Energy stored in a capacitor U = q²/2C

What is capacitor?

In an electric field, a capacitor is a device that stores electrical energy. It has two terminals and is a passive electrical component. Capacitance refers to a capacitor's effect. a capacitor is an electrical energy storage device that consists of two conductors that are isolated from one another and placed near to one another. A straightforward illustration of one such storage device is a parallel-plate capacitor.

Energy stored in a capacitor U = q²/2C
charge on the capacitor is one half q = q/2

U1 = q²/8C

U1 = q²/8C = U/4

Energy stored in capacitor is one-quarter of the total energy.
