In sum, “volt amps” is a warning to proceed with caution.Ĭalculating the required current capacities for datacenters and other power-dense applications is both an art and a science that depends mightily on professional knowledge and experience. They are Power (P) or (W), measured in Watts, Voltage (V) or (E), measured in Volts, Current or Amperage (I), measured in Amps ( Amperes ), and Resistance (R) measured in Ohms. This means that depending on their respective amperage requirements, three 120 VAC servers rated at 200 VA, 400 VA, and 600 VA respectively will not necessarily add up to 1200 VA (1.2 KVA). Ohms Law Calculations With Power In the four tables below, you may enter two of the four factors in Ohms Law. In contrast, AC circuits also have inductive resistance, mostly caused by the build-up and collapse of the current with every 60 Hz excursion of the sinusoidal wave. Thus, watts are a good measure of “real power,” and if you have three 120 VDC devices calculated to work at 200 watts, 400 watts, and 600 watts respectively, then you can just add them linearly to know how much power the circuit requires, which would be 1200 watts (1.2 KW). The resistance in a DC circuit is pure resistance, which is limited to the impedance (measured in ohms) of the conductor(s). Thus, a device drawing 3 amps at 120 volts would be rated at 360 watts or 360 volt-amperes. At a fixed voltage, the formula for converting amps to watts is: amps watts/volts. Watts refer to “real power,” while volt-amperes refer to “apparent power.” Both are simply the product of voltage (V) multiplied by amperage (A). You’ll notice that specs for uninterruptible power systems seldom if ever mention watts (W), but instead speak in terms of volt-amperes (VA). If we put the values of V and I in the above equations from Ohm’s law, we mat get the power as follow as well.What is the difference between watts and volt-amperes? Power (P) in Watts = Voltage (V) in Volts x Current (I) in Amps Let’s plug these values into the formula. To illustrate how to use this formula, we’ll use common wattage and voltage figures.
The formula for this conversion is as follows: Amps Watts / Volts. The basic Amps to Watts calculator uses the Watt’s Law which states that “The total power of an electric circuit is equal to the product of electric current and voltage in that circuit”. Amps, Watts, Volts Calculation Amps to Watts.
For better experience through mobile phones, use the calculator in landscape position. Note 1: If you are on mobile phones, click on the “…” dotes beside the “Advanced Calculator” to select another simple calculator. You may read more about the difference between Star and Delta Connections – Comparison Of Y/Δ. In Advanced Amps to Watts Calculator, you can calculate the electric power in watts, milliwatts or kilowatts from electric current in amperes, milliamperes and kiloamperes and RMS voltage in volts for DC circuits, AC 1-Phase Circuits and AC 3-Phase circuits having the Line to Line voltage ( Delta Connection), Line to Neutral voltage ( Star Connection) and Power Factor (P.F). In Simple Amps to Watt calculator, you can calculate any value of Power in Watts, Current in Amperes and Voltage in Volts by entering any two known values for P, V or I. You can use the following two calculators (Simple and Advance) to calculate the electric power in watts from electric current in amperes and electric voltage in volts.
