Discuss the oscillations of electrical and magnetic energy.

Text Solution

Verified by Experts

The electrical energy of LC oscillator is
`U_(E)=(q^(2))/(2C)=(Q_(m)^(2))/(2C)cos^(2)(omegat+phi)`
The magnetic energy is
`U_(B)=(1)/(2)Li^(2)=(Q_(m)^(2))/(2C)sin^(2)(omegat+phi)`
If the two energies are plotted with an assumption of `phi=0`, we obtain
