Question

If the length of a conductor is increased, its resistivity decreases.

• A. True
• B. False

Answer 1

The correct option is B

False

Resistivity of a substance is the resistance of the conductor of unit length and unit area of cross-section. The resistivity of a substance is a constant at a fixed temperature. But it will be different for different materials. It does not depend upon shape, size, and length of the conductor. Therefore, with an increase in the length of the conductor, the resistivity does not change. Thus, the given statement is false.
