Chapter 12: Electricity and circuits
These NCERT Class 6 Science Chapter 12 notes explain the basic concept of electricity and how it is used in our daily life. The chapter introduces students to electric cells, circuits, and simple electrical components.
NCERT Class 6 Science Chapter 12 – Electricity and Circuits helps students understand how electricity flows through a complete circuit, the role of a switch, and the difference between conductors and insulators. It also explains how an electric bulb works using a filament.
This chapter builds awareness about safe use of electricity and develops a foundation for learning electrical concepts.
1. Meaning of electricity
- Electricity is a form of energy
- Electricity helps us to light bulbs
- Electricity helps to run fans
- Electricity is used to operate machines
- Modern life depends heavily on electricity
2. Electric cell
- An electric cell is a source that produces electricity
- Every electric cell has a positive terminal (+)
- Every electric cell has a negative terminal (–)
- Electricity flows from positive to negative terminal
- Cells are used in many daily life devices
3. Types of electric cells
- Dry cell is commonly used in torches
- Button cell is small and flat in shape
- Button cells are used in watches and calculators
- Different cells produce different amounts of electricity
- Cells must be used carefully to avoid leakage
4. Electric circuit
- An electric circuit is a complete path for electricity
- Electricity flows only when the circuit is complete
- A broken circuit stops the flow of current
- Circuits are used in all electrical devices
- Circuit connects all components properly
5. Components of a simple circuit
- Electric cell provides electricity
- Connecting wires carry electric current
- Switch controls the flow of electricity
- Bulb glows when current passes
- All components must be properly connected
6. Switch
- A switch is used to open or close a circuit
- In ON position, the circuit is complete
- In ON position, the bulb glows
- In OFF position, the circuit is broken
- Switch helps in safe control of electricity
7. Conductors and insulators
- Conductors allow electricity to pass through
- Copper, aluminium, iron are good conductors
- Insulators do not allow electricity to pass
- Plastic, rubber, wood are insulators
- Wires are covered with plastic for safety
8. Electric bulb
- An electric bulb glows when current flows
- The thin wire inside bulb is called filament
- Filament is made of tungsten
- Tungsten becomes hot and produces light
- Bulb converts electrical energy into light energy
9. Safety with electricity
- Never touch electrical switches with wet hands
- Water is a good conductor of electricity
- Do not insert metal objects into plug points
- Always use insulated wires and tools
- Carelessness can cause electric shock
10. Importance of this chapter
- Helps understand basic electrical concepts
- Explains how simple circuits work
- Builds foundation for physics
- Useful for learning electronics
- Important for daily life safety
11. Important keywords and definitions
