Formula to find the current in Single phase AC Electrical Motor

The basic formula for calculating current in the single-phase electrical motor is:

Let's solve an example for it.

Example: Find the current through the single phase, 2 HP motor at 120. The motor has an efficiency of 90% and has the power factor of 85%.

Solution: I = (2 HP * 746) / (120 * 0.9 * 0.85) = 16.25 A
