Electricity Basics and Circuits

Electricity is the flow of tiny charged particles called electrons. When electrons travel along a complete loop, the loop is called an electric circuit. Circuits power almost every device you can think of: lamps, phones, fridges, scooters, traffic lights. To control electricity safely we use a small set of building blocks — a source, a path, a control, and a load — and we wire them up in clever ways.
