An RLC circuit has a resistance of 200 Ω and an inductance of 15mH. Its oscillation frequency
is 7000 Hz. At time t = 0 the current is 25mA and there is no charge on the capacitor. After
five complete cycles the current is:
A. zero
B. 1.8 × 10^−6 A
C. 2.1 × 10^−4 A
D. 2.3 × 10^−3 A
E. 2.5 × 10^−2 A
The answer key says C. Can someone please explain why. Thanks.
