Look around your home and you will see many devices like fans, TVs, washing machines, phones, and lights. Each of these has a small electronic circuit inside that helps it work. A circuit is just a closed path for electricity to move.
To build this path we use tiny parts called electronic components. Every device from a torch to a smartphone uses many of these parts. Some give energy; some only store or control it. All parts can be placed in two main groups: active and passive. If you understand this simple difference, electronics becomes much easier to learn.
