Calculate Power Factor





Formula

The formula to calculate the Power Factor is:

\[ \cos(\Phi) = \frac{R}{Z} \]

Where:

Definition

Power Factor is defined as the ratio of the actual electrical power dissipated by an AC circuit to the product of the r.m.s. values of current and voltage.

Example Calculation

Let's assume the following values:

Using the formula:

\[ \cos(\Phi) = \frac{60}{61.5} \]

Evaluating:

\[ \cos(\Phi) = 0.975609756097561 \]

The Power Factor is 0.975609756097561.
