SUMMARY

The discussion focuses on solving an RLC switch circuit homework problem involving calculations for voltage and current in the circuit. Key parameters include α = 250 and ω = 150, indicating an overdamped response. The solution outlines the voltage across the capacitor (Vcap) and the current through the inductor (Iind) for both t > 0 and t < 0. The final expressions for vc(t) are derived as vc(t) = Ae-50t + Be-450t, with initial conditions leading to the equations A + B = 2V and -50A - 450B = icap(0)/C.

PREREQUISITES

The Attempt at a Solution


Code:
for t > 0:
α = 1/2RC = 250
ω = 1/√(LC) = 150
ω < α    overdamped
s1 = -50
s2 = -450
vc(t) = Ae[SUP]-50t[/SUP] + Be[SUP]-450t[/SUP]
dv/dt = -50Ae[SUP]-50t[/SUP] - 450Be[SUP]-450t[/SUP]

for t <0 :

Vcap = 12(1/6) = 2 V  (open circuit)
Iind = 12/6 = 2 A (short circuit)

t > 0 :

Vcap = 2V
Iind = 2A 
vc(0) = 2V =  A+B
dv(0)/dt = -50A - 450B = icap(0)/C
At this point I get kind of lost and I'm not really sure what to do.

Nevermind, I figured it out.
