Q
Q: A transformer operates on the principle of electromagnetic induction. What is the primary function of a transformer?
Solution: A transformer is designed to increase or decrease the voltage in an AC circuit through electromagnetic induction, depending on the turns ratio of the primary and secondary coils.
Steps: 7
Step 1: Understand that a transformer is an electrical device.
Step 2: Know that it works with alternating current (AC) electricity.
Step 3: Learn that a transformer has two coils: the primary coil and the secondary coil.
Step 4: Recognize that the primary coil receives the input voltage.
Step 5: Understand that the secondary coil delivers the output voltage.
Step 6: Realize that the transformer changes the voltage level based on the number of turns in each coil (turns ratio).
Step 7: Conclude that the main function of a transformer is to either increase (step-up) or decrease (step-down) the voltage in an AC circuit.
