Question

In an oscillating lc circuit, when 75.0% of the total energy is stored in the inductor's magnetic field, (a) what multiple of the maximum charge is on the capacitor and (b) what multiple of the maximum current is in the inductor?

Answer 1

(a) E = ½ Q²/C, so .. (b) E(max) = ½Li² (i=current), so .
