A fully charged capacitor C with initial charge `q_0` is connected to a coil of self inductance L at t=0. The time at which the energy is stored equality between the electric and the magnetic field is:

A

`pi/4 sqrt(LC)`

B

`2pi sqrt(LC)`

C

`sqrt(LC)`

D

`pi sqrt(LC)`

Text Solution

Verified by Experts

In LC circuit, time taken to complete transfer to electrical energy into magnetic energy =`T/4=(2pi sqrt(LC))/4`
`therefore` Time taken at which the energy is stored equally between electric and magnetic field
`=(2pi sqrt(LC))/8=pi/4 sqrt(LC)`
