# How many amps equal 3.5 horsepower?

To answer this question the voltage of the motor is needed.

### How many amps does a 5 hp 240 volt 2 phase motor draw?

First we convert horsepower to watts. 1 Horsepower equals 745.7 watts. Next, using the Ohm's law formula P=IxE where P is power measured in watts; I is current measured in amps; E is voltage measured in volts. Therefore 5(745.7) / 240 = 15.5 amps <<>> The current taken by a motor is highly variable depending on efficiency, power factor and the mechanical load. On a 240 v system you should allow 7 amps per HP…
