Question

For question numbers 1 and 2, two statements are given- one labeled Assertion (A) and the other labeled Reason (R). Select the correct answer to these questions from the codes (i), (ii), (iii) and (iv) as given below
i) Both A and R are true and R is correct explanation of the assertion.
ii) Both A and R are true but R is not the correct explanation of the assertion.
iii) A is true but R is false.
iv) A is false but R is true.
1 Assertion : Following are the structural isomers of butane

Reason: Structural isomers have the same molecular formula but they differ in their structures.

2 Assertion: A fuse wire is always connected in parallel with the mainline.
Reason: If a current larger than the specified value flows through the circuit, fuse wire melts.

Answer 1

Answer:

true

Explanation:

fuse wires are parallel with mainline if a current larger than the specified value flows through the circuit

Answer 2

Answer: Assertion wrong, reason right.

Explanation:

A fuse wire is always connected in series to a circuit. If it is connected in parallel, then the current will get branched, resulting in entering of a large amount of current in the circuit, damaging its components. The main purpose of the fuse is to make sure that the connection breaks before the damage is done. Hence, the assertion is wrong but the reason is right.
