Question

Problem 30.60 Submit My Answers Give Up An L-C circuit consists of an inductor with an inductance of 62.0 mH and a capacitor with a capacitance of 240 F . The initial charge on the capacitor is 6.30 C ' and the initial current in the inductor is zero. Part C What is the maximum energy stored in the inductor? Submit My Answers Give Up Part D When the current in the inductor has half its maximum value, what is the charge on the capacitor? Submit My Answers Give Up Part E When the current in the inductor has half its maximum value, wh at is the energy stored in the inductor? Submit My Answers Give Up

Explanation / Answer

A) The maximum voltage across the cap is given by W=1/2CV^2 or
V=sqrt(2W/C)

B)

C) maximum energy stored in the Inductor is E =1/2LI^2

D)The energy in the circuit is always constant. So when E=1/2LI^2*1/2, Ecap=1/2LI^2*1/2
