$\bold{\boxed{\large{\boxed{\orange{\small{\boxed{\large{\red{\bold{\:ANSWER}}}}}}}}}}$

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Transformer\:}}$

→ Transformer is a device used for conversion of low alternating voltage into high alternating voltage and vice versa.

$\rule{200}{4}$

$\Large\bold\star\underline{\underline\textbf{Principle\:}}$

→ It is based on the principle of mutual induction. That is, when magnetic flux linked with one circuit changes, induced current is produced in neighbouring coil.

$\Large\bold\star\underline{\underline\textbf{Construction\:}}$

→ Note : Check the necessary picture also that is provided with this answer.

→ Transformer consists of two coils wound on a common iron core. Voltage is applied across the primary coil (P). The output is obtained across the secondary coil (S).

→ As voltage (vp) is connected to primary coil, alternating current starts flowing through the coil.

→ As a result, changing magnetic flux gets linked with the coils.

→ Due to change in magnetic flux, an induced e.m.f. is produced in the secondary coil.

Answer 2

Explanation:

transformer is a static device which can transfer power from primary to secondary.

It works on the principle of mutual induction. it works at ac only. in a transformer the voltage, frequecy and phase sequence are constant.

the transformer eqn.is given by

V1/V2=N1/N2=I2/I1=K
