A transformer is a static device; therefore, it does not change voltage up or down with varying frequency.

Q1. What is a transformer?
Ans. 
A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction.
• Consists of primary and secondary coils

• Operates on the principle of Faraday's law of electromagnetic induction

• Used to step up or step down voltage levels

• Examples: power transformers, distribution transformers
