Transformer is a static divices its transfor to Power one
circuit to anther circuit with out change frequency is
called transformer its working mutual induction.

Answer / tamil

t/f is static device which transfers energy from one source
to other source without changing frequency

Answer / phanendra babu

transformer is static device which works on mutual induction
principle and the transformer transfers the power from one
ckt to another ckt and one voltage level to another voltage
level through the magnetic coupling (without any electrical
contact) keeping the frequency constant.

Answer / umar abdulazeez

a transformer is a device that takes energy at one level
and give it out at another level through electromagnetic
induction

Answer / sai

this is the static electric divice the electrical power
transfer to one place to another place without friquence
losses it is working stating electro magnetic induction.

Answer / ramya

transformer is a static device which transfers (steps up or
steps down)one voltage level to another voltage level.

Answer / hasan mehdi

A t/f is static device which consists of two or more
stationay electrick ckt interlinked by a common magnetic
ckt for the perpose of transferring electrical energy b/w
them. The transfer of energy from one ckt to another
without change in frequency.

Answer / sethu raman

trasnformer is on inducton principle. when we supply input
to the primary winding the flux will produce in primary
wining and that flux cuts the secondary winding. due to
this emf the voltage will produce in the secondary
windings. the out put of the secondary will depends on the
secondary winding.when the primary winding is higher then
secondary that is step down trasformer.then the primary
winding is lower then secondary is called as step up
transformers.mostly step up trasformers are only used in
substations for transmitting power.

Answer / sanjeev kumar

A transformer is a device that transfers electrical energy
from one circuit to another through inductively coupled
conductors—the transformer's coils. A varying current in
the first or primary winding creates a varying magnetic
flux in the transformer's core, and thus a varying magnetic
field through the secondary winding. This varying magnetic
field induces a varying electromotive force (EMF)
or "voltage" in the secondary winding. This effect is
called mutual induction.

Answer / saif ali

It's a static device it working principle based on Faraday's law of electromagnetic induction.

If i switch on a transformer but with no load connected to the secondary path.Is the transformer will burn?
