Power in Single-Phase AC Circuits using Current Calculator

Calculate Power in Single-Phase AC Circuits







Formula

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

P=I2Rcos(Φ)

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=I2Rcos(Φ)

Evaluating:

P=2.1260cos(0.5235987755982)

The Real Power is 229.150321841362 watts.
