Hp To Voltage Formula

The following formula is used to calculate the voltage for a given horsepower, current, and efficiency.

V = (HP ร— 746) / (I ร— ฮท)

Variables:

  • V is the voltage in volts
  • HP is the horsepower
  • I is the current in amperes
  • ฮท is the efficiency (as a decimal)

To calculate the voltage, multiply the horsepower by 746, then divide by the product of the current and efficiency.
