:*20 W is consumed by the load. The rest is reactive power that returns to the source.
Example 2: A 20 W laptop is operating on a 120 V AC circuit. You measure the current and get .3 A. What is the power factor for this laptop?
  • Power factor = 20 W ÷ (120 V × .3 A) = .5
  • 20 W is consumed by the load. The rest is reactive power that returns to the source.
