Answer / swathi

a transformer changes electricity from high to low
voltage.It s an electrical device used to convert AC power
at a certain voltage level to AC power at a different
voltage, but at the same frequency.

Answer / sindhu

transformer is a device that is used to transfer energy from
one circuit to another without any change in frequency

Answer / sirisha

The function of a tranformer is to tranfer power from one
ckt to another acting as a coulping device and high or low
output is obtained at secondary winding.

Answer / pawan

normaly transformer two type
1. stap up
2. stap down
So transformer work is premary volt to tranfer maximum volt
in secendry side without electrical cuch only transfer by
electrical wave.

Answer / vinit92

transformer will transfer energy from one circuit to another
circuit without any change in frquency.

frequecy will remain constant while transforming

Answer / rasna kaswan
