Correct Option
The correct option is A is false but R is true
Explanation
Domestic electric circuits are configured to ensure that electrical appliances operate efficiently at a rated voltage and function independently of one another. The choice between series and parallel connections dictates the reliability and voltage distribution within the household network.
Statement-wise Analysis
- Assertion (A): Incorrect. In domestic electric circuits, appliances are connected in parallel, not series. A parallel connection ensures that each appliance receives the same standard voltage (e.g., 220V in India) directly from the mains supply. Furthermore, it allows each device to be switched on or off independently without affecting the operation of other devices in the circuit.
- Reason (R): Correct. In a series circuit, components are arranged in a single continuous loop. Consequently, there is only one path for the current to flow. If one component fails, fuses, or is switched off, the circuit becomes open, and the flow of current stops entirely. This causes all other components in the series to stop working.
Conclusion: Since the Assertion is factually incorrect regarding the nature of domestic connections, but the Reason correctly describes the behavior of series circuits,
A is false but R is true
is the correct answer.Key Takeaway: Domestic circuits utilize parallel connections to provide constant voltage to all appliances and ensure that the failure or switching off of one appliance does not disrupt the power supply to others.
