Answer / dilli babu

The transformer is a static electric divice. It operates in the principle of electro magnetic induction. it transfers the electricity from the two different closed circuits without any physical contact.

The winding ratio will decide the changing the voltage.

If the primary winding having the less number of winding comparing to secondary winding, that transformer is called step up transformer and vise versa.

If the primary winding and secondary winding are in 1:3 ratio then the voltage will be increased to 3 times of primary side voltage.

Answer / partha

A transformer uses the principle of electromagnetic
induction to step up voltage. The power handled remains
constant. Only the voltage and current magnitudes get
changed. A rise in voltage implies a drop in current and
vice-versa

Answer / ankit

Emf equation of transformer is
E=4.44f*flux*N
E directly propotional to no. Of turn in winding. So high no. Of turn volatage is high
