What is the working principle of a transformer
Understand the Problem
The question is asking for an explanation of how a transformer functions, including the principles of electromagnetic induction, the role of the primary and secondary coils, and how voltage changes are achieved.
Answer
Transformers function based on Faraday's law of mutual induction, transferring electrical energy via electromagnetic induction.
The working principle of a transformer is based on Faraday's law of mutual induction. It involves the transfer of electrical energy between two or more coils through electromagnetic induction.
Answer for screen readers
The working principle of a transformer is based on Faraday's law of mutual induction. It involves the transfer of electrical energy between two or more coils through electromagnetic induction.
More Information
A transformer typically consists of two coils: the primary coil, which receives the input voltage, and the secondary coil, which delivers the output voltage. The core between these coils helps to efficiently channel the magnetic flux.
Tips
A common mistake is failing to understand the difference between mutual induction (used in transformers) and self-induction. Unlike self-induction where a change in current in one coil induces emf in the same coil, mutual induction involves separate coils.
