Electric Current using Reactive Power Calculator

Formula

The formula to calculate the Electric Current is:

\[ I = \frac{Q}{V \cdot \sin(\Phi)} \]

Where:

\(I\) is the Current (Ampere)
\(Q\) is the Reactive Power (Watt)
\(V\) is the Voltage (Volt)
\(\Phi\) is the Phase Difference (Radian)

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:

Reactive Power (\(Q\)) = 134 Watt
Voltage (\(V\)) = 130 Volt
Phase Difference (\(\Phi\)) = 0.5235987755982 Radian

Using the formula:

\[ I = \frac{134}{130 \cdot \sin(0.5235987755982)} \]

Evaluating:

\[ I = 2.06153846153846 \text{ Ampere} \]

The Current is 2.06153846153846 Ampere.
