The total reactive power in the load while measuring the reactive power with wattmeter is?

The total reactive power in the load while measuring the reactive power with wattmeter is? Correct Answer √3VLILsinØ

To obtain the reactive power, wattmeter reading is to be multiplied by √3. Total reactive power = √3VLILsinØ.
