1. The zero-input response of a series RLC circuit with R = 50 Ω is
vc(t) = 2e-1000t cos(500t) - 4e-1000t sin(500t)V t>=0
If the initial conditions remain the same, what is the zero-input response when R = 100 Ω?
2. In a parallel RLC circuit the inductor current is observed to be
iL(t) = 20e-20t sin(20t)mA t>=0
Find vC(t) when vC(0) = 0.6 V.
