Study Notes
Electrical Circuits
- An electrical circuit is a network of interconnected electrical components using conductors.
- Conductors enable the flow of electric current.
- Good electrical conductors are also good thermal conductors.
- Metals, particularly copper, are common conductors.
- Liquids, like electrolytes (e.g., salt water), can also conduct electricity.
