Transfer of electric power from primary to secondary in a
transformer takes place
A electrically B magnetically
C electro-magnetically D conductively
Answer Posted / surendra kumar bairwa
C ELECTRO-MAGNETICALLY
it means as showing external ckt. of transformer there are
no energy conversion because INPUT is electrical energy&
OUTPUT is electrical energy.
but internally ckt. electrical ergy converted into megnetic
induction by mutual inductance this evergy converted into
electrical energy.so it is electro-magnetically
