Question
A transformer works on which
principle?Solution
A transformer changes the voltage level using the principle of mutual induction. This is governed by Faraday’s Law, which states that a changing magnetic flux induces an emf in a coil. A transformer uses alternating current to create varying magnetic flux in the core, inducing voltage in the secondary coil. Hence, it operates on Faraday’s Law.
