How To Measure Volts And Amps. 81 rows Ohms Law provides an alternate formula to find volts if amps and the electrical resistance is. Voltage is measured in volts often abbreviated to V.
The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps times the line to line voltage V L-L in volts. T he formula for Amps is Watts divided by Volts. 2400 Watts 10 Amps 240 Volts.
You may see 2 sockets with an A one labeled as A or 10A and one labeled mA.
10 Amps x 120 Volts 1200 Watts. The port marked with A measures amperage. S VA 3 I A V L-L V 3 I A V L-N V Amps to VA calculation. The apparent power S in kilovolt-amps is equal to square root if 3 current I in amps times the line to line voltage V L-L in volts.
