Here are the initial conditions for the above circuit Switch

Here are the initial conditions for the above circuit: Switch #1 is OPEN, Switch #2 is OPEN, the capacitor is discharged, so Qcapacitor = 0.

(a)At time t=0, Switch #2 remains OPEN but Switch 1 is suddenly CLOSED. List the instantaneous values at t=0 of

VR1 = _________ Volts.

IL = _________Amps

VR2 = _________Volts.

IC = _________Amps

VL = _________Volts.

VC = _________Volts

(b) Switch #2 remains OPEN and Switch 1 has now been CLOSED for a long, long time. List the steady-state values of:

VR1 = _________Volts.

IL = _________Amps

VR2 = _________Volts.

IC = _________Amps

VL = _________Volts.

VC = _________Volts

(c) Suppose that both Switch #1 and Switch #2 have been closed for a long, long time Switch #1 is now suddenly OPENED. Immediately after Switch #1 is opened, list the instantaneous values of:

VR1 = _________Volts.

IL = _________Amps

VR2 = _________Volts.

IC = _________Amps

VL = _________Volts.

VC = _________Volts

Solution

(A)

VR1 = 0,   IL =0, VR2 =0, IC =0, VL = maximum, VC =0

(B)

VR1 = V₀,   IL = V0/R1, VR2 =0, IC =0, VL = 0, VC =0

(C)

VR1 = 0,   IL = 0, VR2 =0, IC =0, VL = 0, VC =0
