Webb14 feb. 2024 · In an AC circuit, there may be a phase difference ( ϕ) between voltage and current. The term cos ϕ is called the power factor of the circuit. When the given circuit is inductive, then the current lags behind the voltage and the power factor is termed as lagging power factor. Webb22 sep. 2016 · 1. There is nothing different about a meter that measures AC power in one direction versus two. Think about it. Both the current and voltage go negative and positive over a cycle, even when power is only flowing one way. To determine power, do lots of measurements of the current and voltage over a cycle.
