transformer is a static device which transforms power from
one Circuit ot another circuit with out changing frequency.

Answer / k.vinod kumart

Transformer is 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 / pappu kumar singh

trasfer is a static devices that convert voltage in circuit
to another coupled circuit through inductivelly.

Answer / madhur joshi

Transformer is an electrical static device which transfers
power from one circuit to another without change in
frequency.It can step up or step down the voltage as
desired.

Answer / asphak mohammed

transformer is electro-magnetic machine which transfer
electrical energy from one circuit to another, either at the
same voltage or at different voltage but at the same
frequency it ts static machine

Answer / deepak nain

Transformer is a static device, which is uesd for setup and
step down the voltage without changing frequency.It works
on the principle of Electro Magnetic Induction.

Answer / khan

transfermer is a static device device which can convert voltage one circit to another circit with out frequency changes

Answer / amit koundal

Transformer is a static device, which is uesd for setup and
step down the voltage in without change the frequency.It has
two terminals one output terminal
(primary) & other one
is input terminal(secoundary).is called Transformer.

Answer / nandish.p

transformer is a static device which transforms power from
one ckt 2 another ckt with out changing frequency.

Answer / nandish.p

A TRANSFORMER is a device that transfers electrical energy
from one circuit to another by electromagnetic induction
(transformer action). The electrical energy is always
transferred without a change in frequency, but may involve
changes in magnitudes of voltage and current. Because a
transformer works on the principle of electromagnetic
induction, it must be used with an input source voltage
that varies in amplitude. There are many types of power
that fit this description; for ease of explanation and
understanding, transformer action will be explained using
an ac voltage as the input source.



You learned that alternating current has certain
advantages over direct current. One important advantage is
that when ac is used, the voltage and current levels can be
increased or decreased by means of a transformer.
