Current From HP Formula
The following formula is used to calculate the Current From HP.
I = HP * 746 / (V*PF*n)
- Where I is the Current From HP (amps)
- HP is the total horsepower (hp)
- V is the voltage (volts)
- PF is the power factor
- n is the efficiency
How to Calculate Current From HP?
The following example problems outline how to calculate Current From HP.
Example Problem #1
- First, determine the total horsepower (hp). In this example, the total horsepower (hp) is determined to be 10 .
- Next, determine the voltage (volts). For this problem, the voltage (volts) is measured to be 50 .
- Next, determine the power factor. In this case, the power factor is found to be 3.
- Next, determine the efficiency. For this problem this is .50.
- Finally, calculate the Current From HP using the formula above:
I = HP * 746 / (V*PF*n)
Inserting the values from above and solving yields:
I = 10* 746 / (50*3*.50) = 99.46 (amps)
Example Problem #2
Using the same method as above, determine the variables required by the formula. For this example problem, these are:
total horsepower (hp) = 50
voltage (volts) = 5
power factor = 10
efficiency = .76
Enter these given values into the calculator or above yields:
I = 50 * 746 / (5*10*.75) = 994.66 (amps)
