An oscillating lc circuit consists of a 61.5 mh inductor and a 3.77 μf capacitor. if the maximum charge on the capacitor is 3.56 μc, what are (a) the total energy in the circuit and (b) the maximum current?

0.00739 A

Explanation:

Q = Maximum charge on the capacitor =

C = Inductor capacitance =

L = Inductance = 61.5 mH

I = Current

Maximum energy in capacitor is given by

Total energy in the circuit is

Energy is also given by

The maximum current in the circuit is 0.00739 A

work: w = fd (given)

work done by chet   =50*1 = 50 j

work done by mika =40*2 = 80 j

work done by sara =30*1.5 = 45 j

work done by bill =60*0.5 = 30 j

students in order from the greatest amount of work done to the least is mika> chet> sara> bill

hence option (b) is correct.
