The input to the circuit shown in Figure P 9.2-6 is the voltage of the voltage source, vs. The output is the capacitor voltage v(t). Represent the circuit by a second-order differen- tial equation that shows how the output of this circuit is related to the input for t > 0. Hint: Use the operator method. 1=0 Figure P 9.2-6 Us R C = 0 (1) ww R3 R2 C + 0 (1)
