Explain why there are two sperate circuit one for high power rating appliances other for low power rating appliances?

Question

Answer

It is only because of different appliance use different amount of current and needs different potential difference.

#some big appliances like refrigerator, heater, etc which needs more power and for these appliances we place a circuit having more voltage or potential difference.

#also there are small appliances like bulbs, fan, etc which needs small amount of voltage that's why they needs circuit having small potential difference.

Thank you.. :-)

Answer

Because the current usages of different appliances are different .

high power rating appliances have their seperate plugs and fuse as they draw more current . eg refrigerator , room heater etc

one circuit is for low rating appliances which draw small current.

the sperate plugs gives two advantages :
1. if there is short circuit in one circuit , then only that fuse will get broken . others would not be affected .
2. the high power rating circuit would not draw the current of low rating circuit .

Answer

**Introduction**
In electrical systems, it is common to have two separate circuits, one for high power rating appliances and another for low power rating appliances. This division is essential to ensure the safety and efficiency of the electrical system. Let's explore the reasons behind having separate circuits for different power ratings in detail.

**1. Power Requirements**
- High power rating appliances such as air conditioners, electric heaters, and electric cooktops consume a considerable amount of electrical power to operate efficiently. These appliances typically require circuits with higher voltage and current capacities to meet their power demands.
- On the other hand, low power rating appliances like lamps, televisions, and computers consume significantly less electrical power. These appliances can be adequately powered by circuits with lower voltage and current capacities.

**2. Safety**
- High power rating appliances draw a large amount of current, which generates more heat in the wires. If the wires are not designed to handle this heat load, it can lead to overheating, melting, and potentially cause electrical fires.
- By having a separate circuit for high power rating appliances, heavier gauge wires can be used to handle the increased current flow, reducing the risk of overheating and fire hazards.
- Additionally, high power rating appliances often require specialized outlets with higher ampere ratings to prevent overloading the circuit and causing damage to the electrical system.

**3. Overloading**
- Overloading occurs when the total power demand from multiple appliances exceeds the capacity of a circuit. This can lead to tripped circuit breakers or blown fuses, disrupting the power supply to all connected appliances.
- By segregating high power rating appliances onto a dedicated circuit, the risk of overloading is minimized. This ensures that the circuit can handle the power requirements of these appliances without affecting the operation of low power rating appliances connected to a separate circuit.

**4. Efficiency**
- Separating high and low power rating appliances onto different circuits allows for better load balancing. This means that the electrical load is evenly distributed across circuits, reducing the chances of voltage drops or fluctuations.
- Voltage drops can affect the performance and efficiency of appliances. By ensuring that high power rating appliances have their own circuit, the voltage supplied to low power rating appliances remains stable, optimizing their efficiency and preventing potential damage.

**Conclusion**
Having separate circuits for high and low power rating appliances is crucial for safety, preventing overloading, and ensuring efficient operation of electrical systems. By providing appropriate power capacities and load balancing, these separate circuits help maintain a stable power supply, protect against fire hazards, and optimize the performance of appliances.
