Calculate Power in Single-Phase AC Circuits







Formula

The formula to calculate the Real Power in Single-Phase AC Circuits is:

\[ P = V \cdot I \cdot \cos(\Phi) \]

Where:

Definition

Real Power is the average power in watts delivered to a load. It is the only useful power and is the actual power dissipated by the load.

Example Calculation

Let's assume the following values:

Using the formula:

\[ P = 130 \cdot 2.1 \cdot \cos(0.5235987755982) \]

Evaluating:

\[ P = 236.424935233152 \text{ W} \]

The Real Power is 236.424935233152 W.
