Calculate Active Power (Pa)



Formula

The formula to calculate the Active Power (Pa) is:

\[ Pa = \sqrt{AP^2 - RP^2} \]

Where:

What is Active Power?

Active Power (Pa) is the actual power consumed by an electrical device to perform useful work. It is measured in watts (W) and represents the real power that is converted into heat, light, motion, or other forms of energy. Active power is a crucial parameter in electrical systems as it determines the efficiency and performance of electrical devices.

Example Calculation

Let's assume the following values:

Using the formula to calculate the Active Power (Pa):

\[ Pa = \sqrt{500^2 - 300^2} \approx 400 \text{ watts} \]

The Active Power (Pa) is approximately 400 watts.
