Question

$\text{Assertion (A)}:$ Lightning conductors provide a low resistant path for the electricity to flow into the ground from the sky without damaging the building.

$\text{Reason (R)}:$ Earthing is the process in which electric discharge happens from an uncharged body to a highly charged body.

• A. Both $\text{(A)}$ and $\text{(R)}$ are true, and $\text{(R)}$ is the correct explanation for $\text{(A)}$.
• B. Both $\text{(A)}$ and $\text{(R)}$ are true, but $\text{(R)}$ is not a correct explanation for $\text{(A)}$.
• C. $\text{(A)}$ is true, but $\text{(R)}$ is incorrect.
• D. $\text{(A)}$ is incorrect, but $\text{(R)}$ is correct.

Answer 1

The correct option is C $\text{(A)}$ is true, but $\text{(R)}$ is incorrect.

• A lightning conductor is a long metallic pole or rod placed on the top of a high building. During the times of lightning, it can catch the high current coming from the sky and safely dispose it to the ground without letting it damage the building. This can easily happen only if the rod is made of a good conductor.


• Earthing is a process in which electric charge of an object is transferred to the ground usually by providing a conducting path.

So, $\text{(A)}$ is true, but $\text{(R)}$ is not.
