Two copper wires of the same length have got different diameters
a. which wire has greater resistance?
b. greater specific resistance?

Two copper wires are of the same length, but one is thicker than the other : (a) Which wire will have more resistance? (b) Which wire will have more specific resistance?

Two copper wires are of the same length, but one is thicker than the other. (1) Which wire will have more resistance ? (2) Which wire will have more specific resistance ?

Two wire, one of copper and other of iron, are of the same length and same radius. Which will have more resistance?

Two copper wires of length 1m and 9m have equal resistances. Then their diameters are in the ratio:

Four wires made of same material have different lengths and radii, the wire having more resistance in the following case is
