(1) Which wire will have more resistance?
(2) Which wire will have more specific resistance?
(1) Which wire will have more resistance?
(2) Which wire will have more specific resistance?
Solution:
(1) Thin wire will have more resistance. Since R ∝
(2) Specific resistance of both wire is same because specific resistance depends on the nature of the material which is same in both wires.
(2) Specific resistance of both wire is same because specific resistance depends on the nature of the material which is same in both wires.
