P4.64. Consider the circuit shown in Figure P4.64 in which the switch has been open for a long time prior to t=0 and we are given R=25. a. Compute the undamped resonant frequency, the damping coefficient, and the damping ratio of the circuit after the switch closes. b. Assume that the capacitor is initially charged by a 25-V dc source not shown in the figure, so we have v( 0+ )=25 V. Determine the values of i L (0+) and V'( 0+). C. Find the particular solution for v(t). d. Find the general solution for v(t), including the numerical values of all parameters. IA R w w llll (1) L = 10 xH C = 1000 pF Figure P4.64 P4.65. Repeat Problem P4.64 for R=50 .
