Question

The scientific principle behind the working of a transformer is

• A. Mutual induction
• B. Transmission
• C. Rectification
• D. Amplification

Answer 1

Answer:

A. Mutual induction

• Transformers are capable of either increasing or decreasing the voltage and current levels of their supply,
• without modifying its frequency, or the amount of Electrical Power being transferred from one winding to another via the magnetic circuit.
• So the current is sent through step up transformers to increase the voltage and to push the power over long distances.
