transformer is a static device,transferred the power from one
place to another place with out changing the frequency

Answer / parmod kumar

It is a static device which is working on the principle of
electrocmagnetic induction and transfer voltage from one
level to another level without change in frequency i.e
frequency remain same in primary as well as secondary.

Answer / ashokchakri

it is a m/c which is used to transferred the power from one
place to another place with out changing the frequency

Answer / nid

transformer is a static machine that can change the voltage from one level to another level without any change in power and frequency
ie when vtg reduces in secondary the current increases so as to keep the power in same value
V1I1 =V2I2

IN CASE OF POWER TRANSFORMERS THE SECONDARY CURRENT CAN BE EASILY FOUND OUT BY JUST DIVIDING THE kVA RATING BY .75
