Today Electrical Engineering XYZ shares 4 formulas to calculate current from the horsepowers.
These four formulas will help you to:
Calculate current from HP in DC Circuits
A 24 V DC Motor draws is rated at 1/8 HP. Find the current flowing through it. The recorded efficiency is 95%.
I = ((1/8) * 746) / (24 * 0.95) = 4.08 Amps
Calculate current from HP in single phase ac circuits
A single phase ac motor whose Horsepower is 1 is connected to the voltage source having value 120 V. Find the electrical current if the efficiency is 90%. (The power factor is 0.85)
I = (1 * 746) / (120 * 0.9 * 0.85) = 8.126 Amps
Calculate current from HP in case of three phase circuits
Determine the electrical current which flows through a 1000 watt load, having a power factor 0.9 and which has a 230 V three phase ac source connected to it.
I = ( 1500 watt * 746 / 746) / (230 * 1.73 * 0.9) = 4.18 Amps
