A 230 V supply that pushes 10 amps through a motor delivers 2,300 watts of electrical power, which is about 3.08 horsepower. Quick answer: Multiply the volts by the amps, then divide by 745.7. For example, 230 V at 10 A is 3.084 hp, 120 V at 15 A is 2.414 hp and 400 V…
A 5 V supply across a 1,000 ohm resistor pushes 5 mA, a small current of the kind a status light uses. Quick answer: Divide the voltage by the resistance in ohms, then multiply by 1,000. For example, 5 V across 1,000 Ω is 5 mA, 12 V across 470 Ω is 25.532 mA and…
A single-phase 11,000 V line that carries 200 amps at a power factor of 1 delivers 2.2 megawatts. Quick answer: Multiply the volts by the amps and the power factor, then divide by 1,000,000. For example, 11,000 V at 200 A, PF 1, single-phase is 2.2 MW, 11,000 V at 200 A, PF 0.9, three-phase…
