In the following question, two statements are given - one labelled Assertion (A) and the other labelled Reason (R).
Assertion (A): A fuse wire is always connected in series with the mainline <
Reason (R): If a current larger than the specified value flows through the circuit, fuse wire melts and breaks the circuit.
Select the correct answer to the above question from the following options:
(a) Both A and R are true, and R is the correct explanation of the assertion.
(b) Both A and R are true, but R is not the correct explanation of the assertion
(c) A is true but R is false.
(d) A is false but R is true.
(d) A is false but R is true.
The assertion is false but the reason is true.
Explanation
A fuse is a short length of wire designed to melt and separate in the event of excessive current.
Fuses are not connected to the mainline, rather they are always connected in series with the components to be protected from overcurrent or short-circuit so that when the fuse blows or melts down, it will break the entire circuit and stop the flow of current through the components.
