(a) Resistance is proportional to the wire’s length and inversely proportional to the square of the wire’s radius.
(b) A wire’s specific resistance is not affected by the length or radius of the conductor; it is independent of both.
How does (a) resistance, and (b) specific resistance of a wire depend on its (i) length, and (ii) radius?
How does (a) resistance, and (b) specific resistance of a wire depend on its (i) length, and (ii) radius?
