Here you have the option of calculating the reactive power, the voltage, the current
and the sin φ of e.g. single-phase motors.

Q = U x I x sin φ
Blind Power: Q
Voltage: V
Current: I
sin φ
sin φ hast to be between -1 and 1 sein!
Please fill all mandatory inputs.

Here is an example:

A 230 V single-phase AC motor has a rated current of 8.56 amperes
and a sin φ of 0.9.
What electrical binding power results from these specifications?

Q=U x I x sin φ
Q=230 V x 8.56 A x 0.92
Q=1.811 kVAr

Units of measurement:

Reactive power Q=Kilovolt ampere reactive [KVAr]
Voltage U=Volt [V]
Current i=Ampere [A]
sin phi=no unit of measurement
