Electricity
⭐ MasteredElectricity is the flow of tiny charged particles through a circuit. A circuit must be a complete loop for a bulb to light.
Lightning is a giant spark of static electricity.
All about Electricity
Electricity is the movement of tiny charged particles called electrons through a material. We call this flow an electric current. It travels through wires that act like pathways for the electrons.
For a current to flow, the path must be a closed loop, called a circuit, with a power source such as a battery. If the loop is broken, the electrons stop moving and the device switches off. Materials like metal let electricity pass through easily, while rubber and plastic do not.

Frequently asked questions about Electricity
What is an electric circuit?
A closed loop of wires and parts, such as a battery and a bulb, that lets electricity flow around and make something work.
Why is electricity dangerous?
It can cause serious burns or shocks. Never touch wires, plugs or sockets with wet hands, and always ask an adult for help.
What are conductors and insulators?
Conductors, like copper and metal, let electricity flow. Insulators, like rubber and plastic, stop it from flowing.
