You don't.
If you know how many Amperes in an electrical circuit and also what the total resistance in the circuit is, then EMF (Volts) = current (Amps) x resistance (in Ohms).
EMF stands for Electromotive Force, and its unit of measure is the Volt.
The formula you are looking for is I = W/E.
Multiply the vots by the amps to find the volt-amps. Or divide the volt-amps by the voltage to find the amps.
To convert high voltage (HV) amps to low voltage (LV) amps, you can use the formula: HV amps = LV amps x (LV voltage / HV voltage). By rearranging the formula, you can calculate LV amps by dividing HV amps by the ratio of HV voltage to LV voltage.
At what voltage? If you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
At what voltage? When you know the voltage then, to get the amps those kilovolt-amps contain, you simply divide the kilovolt-amps by the voltage.
To determine the number of amps from watts, you can use the formula: Amps = Watts / Volts. For example, at a standard voltage of 120 volts, 750 watts would equal approximately 6.25 amps (750 watts / 120 volts = 6.25 amps). If the voltage is different, simply divide 750 by that voltage to find the amps.
Watts otherwise known as VA which is voltage X Amps
Watts otherwise known as VA which is voltage X Amps
You just have to divide the watts by the voltage to find the amps. For example 60 watts on a 120 v system would take ½ amp.
To answer this question the voltage must be known. Watts = Amps x Volts.
To find amps if watts and volts are known, use the formula; watts / volts = amps or 5000 / 240 = 20.83 amps
I=V/R In words, Amps equals power divided by voltage. So you need to know voltage. Assuming 120 volts, Amps=5600/120=46.7
