A transformer operates on the principle of electromagnetic induction. What is the primary function of a transformer?

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.

Electromagnetic Induction – The process by which a changing magnetic field induces an electromotive force (EMF) in a conductor.
Voltage Transformation – The ability of a transformer to increase (step-up) or decrease (step-down) voltage levels in an AC circuit.
Turns Ratio – The ratio of the number of turns in the primary coil to the number of turns in the secondary coil, which determines the voltage change.
