Solve this multiple-choice question and check the correct answer with its explanation below.

Answer options

  1. Self Induction
  2. Mutual Induction
  3. Eddy Currents
  4. Thermionic Emission

Correct answer and explanation

Correct answer: Mutual Induction

Explanation: āœ… Correct Answer: B) Mutual Induction šŸ“š Explanation: A transformer consists of two coils, known as the primary and secondary, wound around a common magnetic core. When an alternating current passes through the primary coil, it creates a varying magnetic field that induces a voltage in the secondary coil. This process allows for the efficient stepping up or stepping down of AC voltage for power transmission.
