## How do you calculate amperage for single phase?

Amps calculation with line to line voltage

- I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.
- amps = watts / (√3 × PF × volts) or.
- A = W / (√3 × PF × V) Example.
- I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.

### How do you calculate amps on a motor?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
