The power factor at which transformer operates

The power factor at which transformer operates

Q The power factor at which transformer operates

A) is unity 

B) is 0.8 lag

C) is 0.8 lead 

D) depend upon the power factor of the load

Correct Answer-: depend upon the power factor of the load

Concept

The power factor at which a transformer operate depends opon the power factor of the load. if can be leading pf, lagging pf or unity pf load depending on the load connected on the secondary side of the transformer corresponding to capacitive or resistive load respectively
