The Basic Function of a Transformer is to Change

Q.1 The Basic function of a Transformer is to Change 

(A) The level of the voltage 

(B) The Power level 

(C) The Power Factor

(D) The frequency

Exp-: In a transformer, the energy transfer usually takes place with a change of voltage Supply frequency of output remains the same as that of the input. Power factor and Power level are almost the same on both of the transformers
