Dana India Applications Engineer Interview Questions and Answers

Q1. What is working of transformer
Ans. 
A transformer transfers electrical energy between circuits through electromagnetic induction, adjusting voltage levels as needed.
• Consists of primary and secondary coils wound around a magnetic core.

• Operates on the principle of electromagnetic induction.

• Steps up voltage (step-up transformer) or steps down voltage (step-down transformer).

• Example: A step-up transformer increases voltage from 110V to 220V for transmission.
