State the type of combination used for connecting different electric appliances in domestic circuit . Give reasons?

Question

Answer

Answer
Different electrical appliances in a domestic circuit are connected in parallel because of the following advantages :

(i) If one electrical appliance stops working due to some defect , then all other appliances keep working properly.
(ii) Each electrical appliance has its own switch due to which it can be turned on or turned off independently, without affecting other appliances.
(iii) Each electrical appliance gets the same voltage as that of the power supply line.

Answer

The arrangement of light and various other electrical appliances in domestic wiring because:
In parallel circuit
1. if one electrical appliance stops working due to some defect,then all other appliances keep working normally.
2.each electrical appliance has its own switch due to which it can be turned on or off independently, without affecting other appliances.
3. each electrical appliance gets the same voltage(220V) as that of the power supply line.
4.In the parallel connection of electrical appliances, the overall resistance of the household circuit is reduced due to which the current from the power supply is high.

Answer

Series Combination

In a domestic circuit, different electric appliances are connected in a series combination. This means that the appliances are connected in a sequence, with the current flowing through each appliance one after the other.

Reasons for using a series combination:

1. Uniform current flow: When appliances are connected in series, the same current flows through each appliance. This ensures that each appliance receives the necessary amount of current to function properly.

2. Protection against overload: In a series combination, if one appliance malfunctions or becomes faulty, the current flow is disrupted and all appliances in the circuit stop working. This acts as a safety measure against overload, as it prevents excessive current from flowing through any appliance.

3. Easy control: By using a series combination, it becomes easier to control and switch off individual appliances. Since all appliances are connected in a sequence, turning off one appliance automatically cuts off the current flow to the rest of the appliances.

4. Lower risk of fire: Series combinations reduce the risk of fire in domestic circuits. If a fault occurs in any appliance, the circuit breaks and prevents the possibility of overheating or short circuits that could lead to a fire.

5. Efficient energy utilization: In a series combination, the total voltage of the circuit is divided among the appliances. As a result, each appliance operates at a lower voltage, which can help in saving energy and prolonging the lifespan of the appliances.

6. Economical: The series combination is a cost-effective method of connecting electric appliances in a domestic circuit. It requires fewer wires and fewer connections, reducing the overall cost of installation.

7. Ease of installation: Connecting appliances in a series combination is relatively straightforward and can be easily done during the installation process. This simplifies the wiring and reduces the complexity of the circuitry.

In conclusion, the series combination is the preferred method for connecting different electric appliances in a domestic circuit due to its benefits such as uniform current flow, protection against overload, easy control, lower risk of fire, efficient energy utilization, economic feasibility, and ease of installation.
