Question

Explain about Transformer and explain Its working based on mutual induction.​

Answer 1

Answer:

The working principle of a transformer is based on mutual induction between the primary and secondary circuit linked together by a common magnetic flux. The primary and secondary winding are electrically separate but magnetically linked through a path of low reluctance provided by the iron core.

Explanation:

Answer 2

$\huge \underline \mathsf \red {AnsWer:-}$

It is a device which can change a low voltage of high current into a high voltage of low current and vice-versa.

Its working is based on mutual induction.

• There are two types of transformers.

(i) Step-up Transformers It converts a low voltage of high current into a high voltage of low current.

In this transformer,

Ns > NP, Es > EP and IP > IS

(ii) Step-down Transformer It converts a high voltage of low current into a low voltage of high current.

In this transformer,

NP > NS, EP > ES and IP < IS
