Book Free DemoWe studied that when a metal wire connects two oppositely charged spheres, electrons flow from the sphere, which is at a lower potential, to the sphere at a higher potential. Similarly, if a metallic wire connects two terminals of a battery at a different potential, electrons will flow from the negative terminal to the positive terminal.
Electric circuit:
The path through which electrons flow from one terminal to another terminal of the source is called an electric circuit.
Construction of a circuit:
A simple electric circuit consists of
- A cell or a battery
- Connecting wires
- Bulb
- Switch or key
Simple electric circuit
A cell or a battery:
A cell or a battery acts as a source to the electrical circuit. Generally, we use electricity from the power stations. Example: Neyveli power station.
Connecting wires:
Connecting wires allows the charges to travel from one point on a circuit to another because electricity needs a medium through which to move.
Bulb:
An electric bulb is a device that produces light when electricity is passed between its terminals.
Switch or key:
A switch or key is a device used to start, stop, and regulate the electric current. When the key is switched on, the electrons from the battery flow through the circuit from the negative terminal through the wire, then through the bulb, and finally back to the battery's positive terminal.
