Given:

An L-R-C series circuit has L = 0.200 H, C = 4.00 F, and R = 350 . At t = 0 the current is zero and the initial charge on the capacitor is 2.80 × 104 C.

Questions:

C. How much time does it take for each complete current oscillation after the switch in this circuit is closed?

D. What is the charge on the capacitor after the first complete current oscillation?

Explanation / Answer

(A) A is the maximum charge on capacitor that is 2.80 x 10^-4 C.

Ans: 2.80 x 10^-4 C

(C) w = 1/sqrt(LC)

w = 1/sqrt(0.2 x 4 x 10^-6)

w = 1118 rad/s

T = 2pi / w = 5.62 x 10^-3 sec

(D) after one complete oscillation,

Q = 2.80 x 10^-4 C
