Question: A wattmeter reads 5 KW when its current coil is connected in red phase and its voltage coil is connected between neutral and red phase

A wattmeter reads

5

KW when its current coil is connected in red phase and its voltage coil is connected between neutral and red phase of a symmetrical

3 -

phae system supplying a balanced three

-

phase inductive load of
