8+ AC Power Calculation: Simple Formula & Tool

Determining the power within AC circuits involves more complexity than in direct current (DC) circuits due to the constantly changing voltage and current. Unlike DC, where power is simply the product of voltage and current, AC power calculations must account for the phase relationship between these two values. This phase difference, caused by reactive components like inductors and capacitors, introduces the concept of power factor.
