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....
For a capacitor with AC voltage source, it is said that the
current can be split into a capacitive current component and
resistive current. My professor says the displacement and
capacitive current is not the same, what is the difference between
them?
Qn 1
A capacitor is attached to a battery with a terminal voltage of
V. What happens to the capacitance of the capacitor if it is
attached to a new battery with a terminal voltage of 2V, twice as
large as the previous battery?
The new capacitance is twice as large.
The new capacitance is half as large.
The new capacitance is the same as it was before.

10.An AC voltage source is connected in series to an inductor, a
capacitor, and a resistor of 8 Ohms. At the frequency when the
phase angle is zero, capacitive reactance is 7 Ohms. What is the

What is the peak voltage on a capacitor if the RMS voltage of a
sinusoidal waveform signal across it is 10.00 VAC? Please
make sure to explain the answer.
Construct a capacitor by filling a paper cup with water. What
is the analog of voltage in this case, and what is the
capacitance?
Poke a small hole on the side of the paper cup near the bottom
and let the water drain. How is this similar to an RC circuit?
Decrease the R by making the hole slightly larger in diameter
and re-run the demonstration. How is the rate of water flow
consistent with the new RC value?
