Answers
Answer:
(a) A is incorrect and R is correct
Explanation:
a is incorrect as fuse wire is a safety device
Answer:
However, reason (r) does not provide a correct explanation for assertion (a). The reason why the fuse wire damages the appliances is not because of using the wrong thickness of fuse wire, but rather due to the sudden breakage of the circuit causing a power surge. Therefore, both assertion (a) and reason (r) are correct, but reason (r) is not the correct explanation of assertion (a).
Explanation:
The correct answer is (c) both a and r are correct but r is not the correct explanation of a.
Assertion (a) states that the fuse wire damages the various appliances in household connections, which is true. If the electrical current in the household connection exceeds a certain limit, the fuse wire will melt and break the circuit, protecting the appliances from damage. However, the sudden breakage of the circuit can still cause a power surge, which can potentially damage the appliances.
Reason (r) states that depending on the device/appliance used, the fuse wire of proper thickness has to be used, which is also true. The thickness of the fuse wire is chosen based on the maximum current that the appliance can handle without getting damaged. If the current exceeds this limit, the fuse wire will break and protect the appliance.
However, reason (r) does not provide a correct explanation for assertion (a). The reason why the fuse wire damages the appliances is not because of using the wrong thickness of fuse wire, but rather due to the sudden breakage of the circuit causing a power surge. Therefore, both assertion (a) and reason (r) are correct, but reason (r) is not the correct explanation of assertion (a).
