Enter the current running through the capacitor (amps) and the voltage running through the capacitor (volts) into the calculator to determine the Capacitor Power. 

Capacitor Power Formula

The following formula is used to calculate the Capacitor Power. 

Pc = Ic * Vc

  • Where Pc is the Capacitor Power (watts)
  • Ic is the current running through the capacitor (amps) 
  • Vc is the voltage running through the capacitor (volts) 

How to Calculate Capacitor Power?

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

Example Problem #1:

  1. First, determine the current running through the capacitor (amps). In this example, the current running through the capacitor (amps) is measured to be 245.
  2. Next, determine the voltage running through the capacitor (volts). For this problem, the voltage running through the capacitor (volts) is calculated to be 4.
  3. Finally, calculate the Capacitor Power using the formula above: 

Pc = Ic * Vc

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

Pc = 245* 4 = 980 (watts)


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:

current running through the capacitor (amps) = 401

voltage running through the capacitor (volts) = 55

Entering these values into the formula or calculator above gives us:: 

Pc = 401 * 55 = 22055 (watts)
