Assertion : It is advantageous to transmit electric power at high voltage Reason : High voltage implies high current.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
\(P=V I\) for transmission of same \(P\), high \(V\) means low \(I\) then heat \(\left(=I^{2} R t\right)\) is minimized. High-voltage transmission reduces current, minimizing resistive losses, heat generation, and conductor size, enhancing efficiency. The approach brings cost savings by decreasing construction and maintenance expenses in longdistance power transmission systems. So correct option is (3).

Assertion : Electric field outside the conducting wire which carries a constant current is zero. Reason : Net charge on conducting wire is zero.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
In a conductor with a constant current, the balanced motion of electrons and positive charges leads to a net charge of zero. This absence of an excess charge distribution results in no net electric field outside the wire. So correct option is (1).

Assertion : Insulators do not allow flow of current through them. Reason : Insulators have no free charge carriers.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
Explanation:
Insulators are materials that do not allow the flow of electric current through them because they lack free charge carriers (such as electrons) that can move in response to an electric field. So correct option is (1).

2.5 faraday of electricity is passed through a \(CuS{O_4}\) solution. The number of gram equivalents of copper deposited on the cathode is
1 1
2 1.5
3 2
4 2.5
Explanation:
1 faraday deposits 1 gram equivalent. Hence 2.5 faraday will deposit \(2.5\;g\) equivalent of copper.
