For t < 0, the circuit shown in Figure P5.66 is at DC steady state and the voltage across the capacitor is +7 V. The switch is thrown at t = 0, and:
VS = 12V C = 3,300?F
R1 = 9.1k? R2 = 4.3k?
R3 = 4.3k? L = 16mH
Determine the initial current iL through the inductor and the current i2 through R2 at t = 0+.
