In an oscillating LC circuit, L=3.00 mH and C=2.70 μF. At t=0, the charge on the capacitor is zero and the current is 2.00 A. The maximum charge that will appear on the capacitor will be

Question

Accepted Answer

Correct answer: B. (b) Inductance, L=3 mH Capacitance, C=2.7 μF Current, I=2 A The energy stored in inductor is equal to the energy stored in capacitor. ∴ 12LI^2= Q^22C 3 10^-3 2 2= Q^22.7 10^-6 Q^2=3 4 2.7 10^-9 Q= 3 4 27 10^-10=18 10^-5C

$In an oscillating LC circuit, L = 3.00 mH and C = 2.70 μF . At t = 0, the charge on the capacitor is zero and the current is 2.00 A . The maximum charge that will appear on the capacitor will be$
