Question

Consider the following statements and choose the incorrect one
(a) the resistance of all pure metals decreases on raising the temperature
(b) thin wire has more resistance than a thick wire
(c) the resistance of a wire is inversely proportional to its area of cross section
(d) the resistivity of a wire does not depend upon its dimensions​

Answer 1
