In basic electrical calculations, electricians use the unit of volt-amperes (VA) instead of watts. To keep things simple, let’s just say watts and volt-amperes are synonymous. And because the supply voltage to your home is rated at 240-volt/120-volt, sometimes 120 volts is used in the math, and sometimes 240 volts.
