### What Is Electricity?

**Electricity** is the flow of electric charge through a material, powering everything from lights to power tools.

- **Electric charge:** A property of matter carried by electrons (–) and protons (+).
- **Static electricity:** Charge that accumulates on a surface (e.g., a balloon sticking to hair).
- **Current electricity:** Continuous flow of charge through a conductor.
- **Everyday examples:** Lighting a bulb, running a drill, charging a phone.

Understanding these basics helps you work safely and confidently on home electrical projects.
