Assertion: When the radius of a copper wire is doubled, its specific resistance gets increased.
Reason: Specific resistance is independent of cross-section of material used

Assertion (A): When the radius of a copper wire is doubled, its specific resistance gets increased Reason ( R): specific resistance is independent of cross-section of material used

Choose correct alternative. The radiusof a copper wire is doubled.Its specific resistance

Specific resistance of a wire depends on its

A metallic wire is doubled on itself. How do its resistance and specific resistance change?

When the area of cross-section of a conductor is doubled, its resistance becomes:

The specific resistance of a wire will depend on:
