Homework Statement
Hi
When you set up an LC (tank) circuit there is oscillation due to charge and discharge of capactor and storage of energy in the inductor.
How do you prove that it is simple harmonic? And also how do you prove (mathematically) energy is conserved in an undamped LC oscillation?
Homework Equations
For C: emf= q/c
For L: emf= -L (dI/dt)
The Attempt at a Solution
emf across C=emf across L
ie, q/c + L (dI/dt) = 0
