The resistance of 20 ohm is connected to a source of alternating current rated 110V. 50 Hz find

1. the rms current
2. the maximum instantaneous current in the resistor and
3. the time takes by the current to charge from its maximum value to rms value?

Dear Sindhu,

Aver and RMS current are nearly same. Choose Average for more precision, because power=V*Iavg.

The following is a power simulition result by hsim, which shows Avg~=RMS
