Capacitance in AC Circuits
Capacitance in AC Circuits – Reactance. Capacitive Reactance in a purely capacitive circuit is the opposition to current flow in AC circuits only. Like resistance, reactance is also measured in Ohm''s but is given the symbol X to distinguish it from a purely resistive value. As reactance is a quantity that can also be applied to Inductors as well as Capacitors, …

AC Capacitor Circuits
Remember, the current through a capacitor is a reaction against the change in voltage across it. Therefore, the instantaneous current is zero whenever the instantaneous voltage is at a peak (zero change, or level slope, on the voltage sine wave), and the ...
8.2: Capacitance and Capacitors
There is a limit to how quickly the voltage across the capacitor can change. An instantaneous change means that (dv/dt) is infinite, and thus, the current driving the capacitor would also have to be …

As you have asked about "average" current calculation, and you mention the capacitor charging from zero to within 10% of the supply, cycling a full five times per second, the calculation is very simple and straightforward. However, you didn''t clarify whether you were ...
AC Capacitor Circuits | Reactance and Impedance—Capacitive
Voltage lags current by 90 in a capacitor. Mathematically, we say that the phase angle of a capacitor''s opposition to current is -90, meaning that a capacitor''s opposition to current is a negative imaginary quantity. (See figure above.)

15.2 Simple AC Circuits
The vertical axis on a phasor diagram could be either the voltage or the current, depending on the phasor that is being examined. In addition, several quantities can be depicted on the same phasor diagram. For example, both the current i R (t) i R (t) and the voltage v R (t) v R (t) are shown in the diagram of Figure 15.6(b).(b).
