Calculating amperage from capacitor
So, if the load current is 1 amp and the capacitance is 1 farad, you would expect to see the capacitor terminal voltage fall at 1 volts per second.

How does current flow in a circuit with a capacitor?
$begingroup$ Correct me if I am wrong, but how does the capacitor pass current when it is in series with an AC signal source? The current "passes" but not in the way that you expect. Since the voltage changes sinusoidally, the voltages also changes across the capacitor, which gives rise to an EMF that induces a current on the other side of the capacitor.

Why does the capacitor affect the speed of the motor?
As old oil-filled capacitors dry out, the capacitance goes down and the can''t pass as much AC current. This type of motor is called "capacitor run induction motor". In order to create a rotating magnetic field, the capacitor is there to create a phase shift for one of the two motor windings.

So the current flowing across the capacitor is 180sin(60t) amperes (A). What is the current across a capacitor if the voltage is 5cos(120t) and the capacitance is 0.2F?

Power Factor Correction Capacitors: Part 1 | Consulting
Capacitor failure can, in many cases, be directly linked to harmonic content in the electrical-distribution system. Capacitors are low-impedance devices susceptible to harmonics, and large harmonic currents in the electrical system can over heat the units, causing untimely failure. A capacitor bank, itself, can contribute to harmonics problems.
