Q: A transformer works on the principle of:
Solution:
A transformer operates on the principle of electromagnetic induction, transferring energy between coils through a changing magnetic field.
Steps: 6
Show Steps
Step 1: Understand that a transformer has two coils of wire, called the primary coil and the secondary coil.
Step 2: Know that when electricity flows through the primary coil, it creates a magnetic field around it.
Step 3: Realize that this magnetic field changes as the electricity changes (alternating current).
Step 4: Understand that this changing magnetic field passes through the secondary coil.
Step 5: Learn that the changing magnetic field induces (creates) an electric current in the secondary coil.
Step 6: Conclude that this process of creating electricity in the secondary coil from the primary coil is called electromagnetic induction.
