An RLC circuit consists of a 25 mH inductor, a 0.001 µF capacitor and a variable resistor connected in series.
The initial charge on the capacitor at t = 0 when the switch is closed is 1 mC.
What is the critical resistance Rc for this circuit (the resistance that makes the oscillation of charge critically damped)?
Also, generate three plots of the charge on the capacitor vs. time:
1.) Q(t) from t = 0 to t = 1 ms for R = 0.01 x Rc
2.) Q(t) from t = 0 to t = 1 ms for R = 0.1 x Rc
3.) Q(t) from t = 0 to t = 1 ms for R = Rc from t = 0
where the assigned loop current leaves the voltage source. If current leaves the voltage source at its positive terminal, the voltage would be positive and if it leaves the voltage source at its negative terminal,the voltage would be negative.
