I'm new to the electrical field and trying to understand how a transformer works. I've read a lot of material online, but some of it seems overly complex and confusing. Could someone explain the working principle of a transformer in a simple and easy-to-understand way?

As you are new to electrical concepts, this explanation should be perfect for you.
A transformer works by transferring electrical energy from one circuit to another using electromagnetic induction. It consists of two coils of wire:
- Primary Coil – Receives the input voltage.
- Secondary Coil – Delivers the output voltage.
When alternating current (AC) flows through the primary coil, it creates a changing magnetic field around it. This magnetic field induces a voltage in the secondary coil, allowing electricity to be transferred without direct contact.
- If the secondary coil has more turns than the primary coil, the voltage increases (Step-up Transformer).
- If the secondary coil has fewer turns, the voltage decreases (Step-down Transformer).
Transformers are used in power transmission to efficiently transfer electricity over long distances while minimizing energy loss.
