In a single-phase capacitor start-and-run motor, the minimum number of capacitors to be used in it is:

The meter constant of an energy meter will be given in:

In the two wattmeter method, the readings of the two wattmeters are 500W, 500W respectively. The load power factor in a balanced 3-phase 3-wire circuit is:

A magnetic circuit is applied with a current that changes at a rate of 5 A/sec. The circuit has an inductance of 2H, then the self-induced EMF is

The annual load factor of a generation station is equal to
