Answer / abhijit

transformer is a static device which transfer the power
from one ckt to another ckt without changing freq.

Answer / bose

A transformer is a static device which step ups or step
downs the applied voltage by keeping the frequency and the
power same in both primary & secondary side.

Answer / md arif khan

A transfermer is a electrical device which convered high
tention TO low tention (HT TO LT) the applied voltage by
keeping the frequency and the power same in both HT & LT
SIDE

Answer / goutham.neerati

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.
