The specific resistance of a wire

(a) Varies with its length

(b) Varies with its area of cross-section

(c) Varies with its mass

(d) does not depend upon its mass, length and area of cross-section

Specific resistance of a wire depends on its

Specific resistance of a wire depends on its

When the length and area of cross-section both are doubled, then its resistance

Resistance of the conductor of length 5m and area of cross -section 4 mm^(2) s 0.02 Omega . Its resistivity is

A wire of given metarial having length l and ares of cross-section A has a resistance of 4 Omega . What would be the resistance of another wire of the same meterial having length l/2 and area of cross-section 2A ?

on heating a cylindrical metallic rod, its length increases by 2% . Then area of cross section of rod will

Resistance of a conductor of length l and area of cross-section A is R. If its length is doubled and area of cross-section is halved, then find its new resistance.

Resistance of a conductor of length l and area of cross-section A is R. If its length is doubled and area of cross-section is halved, then find its new resistance.

A wire of resistance 4 Omega is stretched to twice its original length. In the process of stretching, its area of cross-section gets halved. Now, the resistance of the wire is

A cylindrical conductor of length l and uniform area of cross-section A has resistance R . Another conductor of length 2 l and resistance R of the same material has area of cross-section :
