1. Alternating Currents
Electricity Tutorial 9

2. Power in AC Circuits Average power = effective volts × effective amps
Voltage and current are both in phase.
When the voltage is at a peak positive value, the current is at peak positive value.
When the voltage is at a peak negative value, the current is at peak negative value.
The power is always positive.
The maximum power is given by:
Minimum power = 0.
Average power =
Average power = effective volts × effective amps
Therefore
