Questions & Step-by-Step Solutions
A transformer operates on the principle of electromagnetic induction. What is the main purpose of a transformer?
Step 1: Understand that a transformer is a device used in electrical circuits.
Step 2: Know that it works based on a principle called electromagnetic induction.
Step 3: Learn that the main purpose of a transformer is to change voltage levels.
Step 4: Recognize that it can either increase (step-up) or decrease (step-down) the voltage.
Step 5: Understand that this change in voltage depends on the number of coils (turns) in the transformer.
Electromagnetic Induction – Transformers operate on the principle of electromagnetic induction, where a changing magnetic field induces voltage in a coil.
Voltage Transformation – The main purpose of a transformer is to increase or decrease voltage levels in an AC circuit based on the turns ratio of its coils.
