Question

These questions consist of two statements each, printed as assertion and reason. While answering these questions you are required to choose anyone of the following four responses.

Assertion: Long distance power transmission is done at high voltage.

Reason: At high voltage supply power losses are less.

• A. If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.
• B. If both Assertion and Reason are true but the Reason is not the correct explanation of the Assertion.
• C. If Assertion is true statement but Reason is false.
• D. If both Assertion and Reason are false statements.

Answer 1

The correct option is A If both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

Long distance power transmission is done at high voltage.

Since power loss

$P_{loss}=I^{2}R={\left(\frac{P}{V}\right)}^{2}R$

Here P & R are fixed conditions so less power will be lost if high voltage V are used.

At high voltage supply power loss are less.

Both assertion and reason are correct and reason correctly explains assertion

Option A is correct.
