Current in AC Capacitor

When a capacitor and a resistor are connected to AC lines, a constant current can be maintained through the resistor, so long as the Rectance of the capacitor is greater than the resistance of the resistor. The current flow depends on the value of the capacitor assuming that the input voltage is greater than the output voltage.

The current through the resistor R is

I RMS = V1 x X C

Where X C is the Rectance of the capacitor
