Tutorial: Convert Watts to VA, convert VA to Watts,kva to amps, kw to kva, amps to kva. V is the RMS voltage and A the RMS amperage. Voltage is like the pressure in a garden hose with a hand operated spray nozzle at the end. How to convert apparent power in volt-amps (VA) to real power in watts (W). Voltampere, VA, er måleenheten for skinneffekt eller kapasitet i. Voltampere og watt har samme dimensjon (energi per tidsenhet); enhetene har dog ulike . Many people are confused about the distinction between the Watt and Volt-Amp (VA) measures for UPS load sizing.
The three most basic units in electricity are voltage (V), current (I, uppercase i) and resistance (r). Voltage is measured in volts, current is measured in amps . Electronics have both maximum watt ratings and maximum VA (volt-ampere) ratings; and neither the watt nor the VA rating of a UPS may be . So with this analogy in mind the definitions below for amp, volt and watt should.
