Here you have the possibility to calculate the active power, voltage, current and cos φ of
e.g., AC motors.

P = U x I x cos φ
Power: P
Voltage: V
Current: I
cos φ
cos φ has to be between -1 and 1 sein!
Please fill all mandatory inputs.

Here is an example:

A single-phase 230 V AC motor (or single-phase motor) has a rated current
of 3.506 amperes and a cos φ of 0.93.
What electrical power results from these specifications?

P=U x I x cos φ
P=230 V x 3.506 A x 0.93
P=0.75 kW

Units of measurement:

Active power P=Kilowatt [kW]
Voltage U=Volt [V]
Current i=Ampere [A]
cos φ=none
