Energy in a Capacitor and Inductor:
Mechanical Analogy: Mass Spring System
LC circuits oscillate much in the same way a mass spring system oscillates
Conservation of Energy:
Solving the Loop Equation – Analogy to Mass-Spring System
(δ is the initial phase angle of the oscillation)
Often set δ= 0, where at t = 0, the initial
condition is chosen to be x = xmax
