When it comes to domestic wiring, the parallel arrangement is the preferred method for several important reasons. The correct answer to your question is (A) For getting the same potential difference across each electrical appliance. Let's delve into why this is the case and how it benefits our everyday use of electrical devices.
Understanding Parallel Wiring
In a parallel circuit, each electrical appliance is connected directly to the power supply. This means that every device receives the same voltage, or potential difference, from the source. This is crucial for the proper functioning of most household appliances, which are designed to operate at a specific voltage level.
Benefits of Parallel Arrangement
- Consistent Voltage: Each appliance gets the same voltage, ensuring that they operate efficiently. For example, if you have a 230V appliance, it will receive exactly 230V regardless of how many other devices are connected.
- Independent Operation: If one appliance fails or is turned off, it does not affect the others. In contrast, in a series circuit, if one device fails, the entire circuit is interrupted.
- Flexibility in Usage: You can add or remove appliances without disrupting the entire system. This is particularly useful in homes where appliances are frequently changed or upgraded.
Real-World Example
Consider a household with several devices like a refrigerator, a microwave, and lights. If these were wired in series, turning off one device would cut power to all the others. This would be highly impractical, especially in a kitchen where multiple appliances are often used simultaneously. With parallel wiring, each device can be used independently, ensuring convenience and functionality.
Voltage Considerations
In a parallel circuit, the voltage across each appliance remains constant and equal to the source voltage. This is essential because appliances are designed to operate at specific voltages. For instance, if a light bulb is rated for 60V, it must receive that voltage to function correctly. If the voltage were to vary, it could lead to underperformance or even damage to the appliance.
Conclusion
In summary, the parallel arrangement in domestic wiring is primarily used to ensure that each electrical appliance receives the same potential difference. This setup not only enhances the efficiency of the devices but also provides safety and convenience in everyday use. Understanding this concept is fundamental for anyone looking to grasp the basics of electrical systems in homes.
