Electric Current using Real Power Calculator

Formula

The formula to calculate the Electric Current using Real Power is:

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

Where:

\(I\) is the Current (A)
\(P\) is the Real Power (W)
\(V\) is the Voltage (V)
\(\cos(\Phi)\) is the Phase Difference (rad)

Definition

Current or AC is an electric current which periodically reverses direction and changes its magnitude continuously with time in contrast to direct current which flows only in one direction.

Example Calculation

Let's assume the following values:

Real Power (\(P\)) = 235 W
Voltage (\(V\)) = 130 V
Phase Difference (\(\Phi\)) = 0.5235987755982 rad

Using the formula:

\[ I = \frac{235}{130 \cdot \cos(0.5235987755982)} \]

Evaluating:

\[ I = 2.08734328091634 \text{ A} \]

The Current is 2.08734328091634 A.
