AP State Board Syllabus 6th Class Science Notes Chapter 10 Basic Electric Circuits
→ The cell is the source of electrical energy in a torchlight.
→ The cell has two terminals, (+) and (-).
→ Do not connect the two terminals of a cell with a single wire.
→ The bulb consists of a filament that gives light and two terminals.
→ A circuit consists of a cell (power source), a bulb, and connecting wires.
→ An electric circuit provides a complete path for electricity to flow between the cell and the bulb.
→ Electricity requires a closed path for it to flow.
→ A switch helps us to allow or break the flow of electricity in a circuit.
→ The flow of electricity in a circuit is called a current.
→ A torchlight consists of a cell, a bulb, and a switch.
→ Substances that allow the flow of electricity are known as conductors of electricity.
→ Substances that do not allow the flow of electricity are known as insulators.
→ The electric bulb was invented by Thomas Alva Edison.
→ Electricity: The flow of electrons is known as electricity.
→ Cell: Cell is the source of energy. An electric cell is a sort of container that produces electricity from the chemical stored inside it.
→ Bulb: An electric bulb is a device that produces light when electricity is passed through its terminals. There are different types of bulbs.
→ Fused bulb: A bulb is said to be fused if the filament gets broken. The fused bulb does not glow.
→ Terminals: The terminal is a point of connection for closing an electric circuit, Cell has two terminals ‘+’ and ‘-‘. The bulb also has two terminals ‘+‘ and ‘-‘.
→ Filament: The metal resistance wire inside a bulb that transfers electrical energy to light.
→ Switch: A device for making and breaking the connection in an electric circuit.
→ Circuit: An electrical circuit is a path in which electrons from a current source flow.
→ Conductor: The material which permits (allow) the electric current to pass through it.
→ Insulator: The material which resists the current to flow through them.
→ Tungsten: A type of metal used for making filaments.
→ LED bulb: LED stands for the light-emitting diode. It is an energy efficiency bulb.
→ Electric shock: A reflex response to the passage of electric current through the body.
