Study Notes
Electricity and Energy
- Electricity is a convenient way of delivering energy
- Energy can be used in various ways, including lighting, heating, and powering devices
Electric Charge and Current
- Electric current is a flow of tiny particles called electrons
- Electrons carry a tiny electric charge, which is negative (-)
- There are two types of electric charge: negative (-) and positive (+)
- A flow of charge is called a current
Conductors and Insulators
- Metals are good conductors because some electrons are only loosely held and are free to move through the material
- Insulators do not allow current to flow easily because electrons are tightly held to their atoms
- All materials, including conductors and insulators, are made of atoms that contain electrons
