Directions: In the following questions, a statement of assertion (A) ...
Assertion: When the length of a wire is doubled, then its resistance also gets doubled.
Reason: The resistance of a wire is directly proportional to its length.
The correct answer is option A: Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
Explanation:
Resistance and Length of a Wire:
Resistance is the opposition offered by a material to the flow of electric current. It depends on various factors such as the material of the wire, the cross-sectional area of the wire, and the length of the wire.
Direct Proportionality:
When two quantities are directly proportional, it means that if one quantity doubles, the other quantity also doubles. In this case, the assertion states that when the length of a wire is doubled, its resistance also gets doubled.
Explanation of the Assertion and Reason:
The reason provided in the statement correctly explains the assertion. The resistance of a wire is directly proportional to its length. This means that if the length of a wire is doubled, its resistance will also be doubled. This relationship holds true as per Ohm's law, which states that the resistance (R) is directly proportional to the length (L) of the wire, given that the material and cross-sectional area remain constant.
Ohm's Law:
Ohm's law states that the current (I) flowing through a conductor is directly proportional to the voltage (V) applied across it and inversely proportional to the resistance (R) of the conductor. Mathematically, Ohm's law can be represented as: V = I * R.
Conclusion:
Based on the explanation above, it can be concluded that when the length of a wire is doubled, its resistance also gets doubled. This is because the resistance of a wire is directly proportional to its length, as stated in Ohm's law. Therefore, both the assertion and reason are true, and the reason correctly explains the assertion.
Reason: The resistance of a wire is directly proportional to its length.
The correct answer is option A: Both assertion (A) and reason (R) are true, and reason (R) is the correct explanation of assertion (A).
