A Bulb connected to an electric cell
A Bulb Connected to an Electric Cell
Filament: In an electric bulb, there is a thin tiny wire inside the glass cover. This is called a filament.
Terminal: All types of electric cells have two terminals:
- a positive terminal
- a negative terminal
Wire :
- An electric wire is a conducting path in an electric circuit, through which current flows.
- It is usually made out of a metal that is a good conductor of electricity.
Electric Bulb and its Working:
- It consists of a thin wire that glows due to the passage of current. This is known as the filament.
- An electric circuit provides a closed path for the current to flow. The terminals of the bulb are connected by wires to the electric cell.
- Sometimes the bulb does not glow as the filament gets fused (breaks) due to overheating.
