An LRC Circuit Is at Critical Damping with R =

Multiple Choice

An LRC circuit is at critical damping with R = 100 Ω. Starting from its maximum value, the charge on the capacitor drops to 50% of its value in a time t = 5 ms. What are the values of the inductance L and the capacitance C?

A) L = 0.36 H, C = 0.144 mF
B) L = 2.67 H, C = 1. 25 mF
C) L = 0.03 H, C = 0. 3 mF
D) L = 1.17 H, C = 8.1 mF
E) L = 5.12 H, C = 0. 06 mF
