The formula to calculate the Real Power in Single-Phase AC Circuits is:
P=I2⋅R⋅cos(Φ)
Where:
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.
Let's assume the following values:
Using the formula:
P=I2⋅R⋅cos(Φ)
Evaluating:
P=2.12⋅60⋅cos(0.5235987755982)
The Real Power is 229.150321841362 watts.
