# A ½-hp Motor Amperage Requirement Calculation

## What is the required amperage for a ½-hp motor that operates on 120 volts?

## Amperage Requirement Calculation Details

**Power (P):** The power rating of the ½-hp motor can be calculated by converting the horsepower to watts. Since 1 hp is equivalent to 745.7 Watts, half of that would be 372.85 Watts.

**Amperage (I):** To find the required amperage, we use the formula I = P / V, where the power is 372.85 Watts and the voltage is 120 Volts. By substituting these values into the formula, we get:

I = 372.85 W / 120 V = 3.1071 A

Therefore, to operate the ½-hp motor on 120 volts, it requires an amperage of approximately 3.11 Amperes.
