Types of Circuits
1. Series Circuit:
1. Series Circuit:
All components are connected one after the other.
If one component stops working, the entire circuit breaks.
Example: Old decorative lights – if one bulb fuses, all stop working.
Analogy:
A series circuit is like a train with connected compartments. If one compartment disconnects, the entire train stops.
2. Parallel Circuit:
2. Parallel Circuit:
Components are connected in separate branches.
If one component stops working, others continue functioning.
Example: Modern house wiring – if one light turns off, others still work.
Analogy:
A parallel circuit is like multiple roads leading to the same place. If one road is blocked, others can still be used.
3. Open Circuit
3. Open Circuit
An open circuit is an incomplete circuit where electricity cannot flow because there is a break in the pathway.
Key Characteristics:
The circuit is not connected completely.
No current flows through the circuit.
Electrical devices like bulbs or fans will not work in an open circuit.
Example:
A switched-off torch is an open circuit because the switch is not allowing electricity to flow.
If a wire in a circuit is cut or a bulb is removed, the circuit becomes open.
Analogy:
An open circuit is like a broken bridge—vehicles (electricity) cannot pass through.
4. Closed Circuit
4. Closed Circuit
A closed circuit is a complete circuit where electricity flows continuously, allowing devices to function properly.
Key Characteristics:
The circuit is fully connected with no breaks.
Current flows through the wires and components.
Electrical devices such as bulbs or fans will work in a closed circuit.
Example:
A switched-on torch is a closed circuit because electricity flows from the battery to the bulb.
When you turn on a room light using a switch, you complete the circuit, allowing current to flow.
Analogy:
A closed circuit is like a continuous water pipeline—water (electricity) flows smoothly from one point to another.
