Enter the power (watts) and the voltage (volts) into the calculator to determine the Current From Power. 

Current From Power Formula

The following formula is used to calculate the Current From Power. 

Ifp = P/V

  • Where Ifp is the Current From Power (amps)
  • P is the power (watts) 
  • V is the voltage (volts) 

How to Calculate Current From Power?

The following two example problems outline how to calculate the Current From Power.

Example Problem #1:

  1. First, determine the power (watts). In this example, the power (watts) is measured to be 5015.
  2. Next, determine the voltage (volts). For this problem, the voltage (volts) is calculated to be 40.
  3. Finally, calculate the Current From Power using the formula above: 

Ifp = P/V

Inserting the values from above and solving the equation with the imputed values gives: 

Ifp = 5015/40 = 125.375 (amps)

Example Problem #2: 

Using the same process as example problem 1, we first define the variables outlined by the formula. In this case, the values are:

power (watts) = 411

voltage (volts) = 50

Entering these values into the formula above gives : 

Ifp = 411/50 = 8.22 (amps)
