Transformer works on the principle of
Correct answer: C. Mutual induction
- A. Lenz's law
- B. Faraday's law
- C. Mutual induction
- D. Law of conservation of power
Explanation
A transformer operates based on the principle of mutual induction. Mutual induction is the process where a changing current in one coil (primary coil) induces an electromotive force (EMF) and a current in a nearby coil (secondary coil) when they are in close proximity. The transformer utilizes this mutual induction to transfer electrical energy from one coil to another without direct electrical connection.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
