Given the information provided in Problem 5.73, what are the values of R and L so that the peak at 20?/3?s is vC = 0.7VS? Assume C = 1.6?F.
Problem 5.73
Assume that the circuit shown in Figure P5.70 is underdamped, and for t < 0, the circuit is in DC steady state with vC = VS . After the switch is thrown at t = 0, the first two zero crossings of the capacitor voltage vC occur at t = 5?/3?s and t = 5? ?s. At t = 20?/3?s, the capacitor voltage vC peaks at 0.6VS . If C = 1.6?F, what are the values of R and L?
