The figure below shows three cylindrical copper conductors along with their face areas and lengths. Compare the resistance and the resistivity of the three conductors. Justify your answer.

The figure here shows three cylindrical copper conductors along with their faces areas and lengths. Rank them according to the current through them, greatest first, when the same potential differnce V is placed across their lengths.

Figure shows graph between I and V for two conductors A and B. Their respective resistances are in the ratio.

Arrange the resistance of three metallic conductors A, B, C in ascending order. B

Figure shows three current carrying conductors and three imaginary loops. Calculate the current enclosed by each of the loops.

A conductor of length l and area of cross-section A has a resistance R then its specific resistance is

A condutor of length l is stretched such that its length increases by 10 % calculate the percentage change in the resistance of the conductor.
