Power in Single-Phase AC Circuits using Voltage Calculator

Calculate Power in Single-Phase AC Circuits







Formula

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

\[ P = \frac{V^2 \cdot \cos(\Phi)}{R} \]

Where:

Definition

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

Example Calculation

Let's assume the following values:

Using the formula:

\[ P = \frac{130^2 \cdot \cos(0.5235987755982)}{60} \]

Evaluating:

\[ P = 243.930488732617 \text{ W} \]

The Real Power is 243.930488732617 W.
