transformer is an electrostaitc device which transfer
electrical energy from one place to another place through
constant flux. it is useful for step-up & step-down the
voltage levels (without changing the frequency)

Answer / nukman hakkim

transformer is a electrical static equipment,it transfer
energy to one electrical circuit to other electrical.
circuit(one circuit to other coil)with out changing frequency
it has a two winding primary winding and secondary winding
or(output and input)step up and step down voltage depending
up on the turns of coil.
