Given the information provided in Problem 5.42, explain how to modify the circuit so that the first two peaks occur at 5π µs and 15π µs. Assume that C cannot be changed.

Problem 5.42

Assume that the circuit shown in Figure P5.42 is under damped and that the circuit initially has no energy stored. It has been observed that, after the switch is closed at t = 0, the capacitor voltage reaches an initial peak value of 70 V when t = 5π/3 µs, a second peak value of 53.2 V when t = 5π µs, and eventually approaches a steady-state value of 50 V. If C = 1.6 nF, what are the values of R and L
