Question

In a low power factor wattmeter the compensating coil is connected

Answer 1

In low power circuit, the value of current is high, and that of the power islow. The high-value current causes the error in the Wattmeter reading. For reducing the error, the compensationcoil is used in the circuit. Thecompensating coil compensates the error in the circuit which induces because of low power factor.
