Option 2 is correct
Explanation:
- A number of turns in the secondary coil and primary coil of a self-designed transformer.
- To change the A.C voltage. a transformer is used. It is used for both low and high circuit flow
- It uses the principle of mutual induction, in which the magnetic flux changes with the changing coil in the circuit
