When a resistor has an AC current flowing through it, what happens to the flow of power during an AC cycle? The resistor uses electrical power at a steady rate during the entire cycle. The resistor supplies electrical power in pulses. The resistor uses electrical power during part of the cycle, but supplies electrical power when the current reverses direction The resistor supplies electrical power at a steady rate during the entire cycle. The resistor uses electrical power in pulses.
