What are The Difference Between Volt and Watt

Actually both watts (W) and volt-amperes (VA) are units of measurement for electrical power. Watts state to “real power,” while volt-amperes refer to “apparent power.” Usually,electronic products show one or both of these values to provide the actual information about how much energy has been consumed or how much current has been drawn. Each of these
values can be used for several purposes.

As watt refers to the real power so it can be defined as the power that performs work or generates heat. Power in watts is the rate at which energy is consumed (or generated). One watt is one joule (energy) per second (1 W = 1 J/s).

As it is defined as the apparent power in VA so is being used to simplify power ratings, making it easier to calculate current drawn. Since VA = RMS volts x RMS amps, RMS (Root mean square) we can divide the VA rating by RMS voltage to get the RMS current the device will draw.
