Briefly explain power factor and one common misconception about it.

## Power Factor **Power factor** is the ratio of real power (doing useful work) to apparent power (total power supplied) in an AC electrical system. It ranges from 0 to 1 (or 0% to 100%) and indicates how efficiently electrical power is being converted into useful work. **Formula:** Power Factor = Real Power (kW) / Apparent Power (kVA) A power factor of 1.0 (unity) means all the power is being effectively used. Lower values mean more wasted energy circulating between the source and load without doing useful work. ## Common Misconception **"Low power factor means you're using more energy."** This is incorrect. Power factor doesn't change how much *real power* (kW) your equipment consumes to do work. A motor running at 0.7 PF uses the same real energy as one at 1.0 PF to perform the same task. However, low power factor *does* mean: - Higher current must flow through wires to deliver the same real power - This causes greater losses in the distribution system - Utilities may charge penalties because they must supply larger currents and size equipment accordingly So while your equipment's energy consumption stays the same, low power factor creates inefficiencies in the *delivery* of that power.
