Energy to power formula
WebHow to calculate power factor. To calculate power factor, you need a power quality analyzer or power analyzer that measures both working power (kW) and apparent power (kVA), and to calculate the ratio of kW/kVA. The power factor formula can be expressed in other ways: PF = (True power)/ (Apparent power) OR. PF = W/VA. WebIncludes 6 problems. Problem Set WE3: Work and Power 1.
