Develop a series RLC circuit that increases the capacitor
voltage to the source voltage as fast as possible with no more than
a 20% overshoot. The source voltage is 99V, the capacitance is 9F
the and the inductance is 23 H. You can adjust the resistance since
that the inductance are the two easiest parameters to adjust. I
suggest you find ω0 for your circuit and the value of R that
results in a critically damped circuit. Plot this vs....
