# AC Power Calculator

This page shows the online AC Power calculator to calculate the AC current in a circuit for the given Power Factor Angle, Voltage, Current, etc. In Direct Current, the electric charge flows in only one direction. Whereas in Alternating Current, Electric charge in alternating current changes direction periodically. AC current calculator needs the values of Power Factor Angle in degrees, voltage, and current in amperes. This AC voltage calculator can accept inputs in different units.

#### Formula:

For Single Phase
P = V × I × cos(θ)
V = P / (I × cos(θ)
I = P / (V × cos(θ)
For Three Phase
P = √3 × V × I × cos(θ)
V = P / (3 × I × cos(θ)
I = P / (3 × V × cos(θ)
**Where,**
P = Power
θ = Power Factor Angle
V = Voltage
I = Current
The above AC power calculator is designed in a user friendly manner to perform calculations. Results given by this AC current calculator are higly reliable.
