The formula to calculate the Real Power is:
\[ P = I_{rms} \cdot V_{rms} \cdot \cos(\Phi) \]
Where:
The Real Power \(P\) 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:
\[ P = 4.7 \cdot 57.5 \cdot \cos(0.5235987755982) \]
Evaluating:
\[ P = 234.043365372745 \text{ W} \]
The Real Power is 234.043365372745 W.
