It is often confused about the usage of terms apparent power and real power, Volt-Ampere (VA) and Watt (W). Especially power supply unit manufacturers specify their device ratings in VA, but the actual load such as bulb, fan, TV, Fridge, etc. are specified with power rating in watts (W). The real power is the actual […]
