Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?

Resistance is given by the equation,

R = ρ l/A

where,

ρ is the resistivity of the material of the wire,

l is the length of the wire

A is the area of the cross-section of the wire.

From the equation, it is evident that the area of the cross-section of wire is inversely proportional to the resistance. Therefore, thinner the wire, more the resistance and vice versa. Hence, current flows more easily through a thick wire than a thin wire.

Answer:

R=V/I......1

R=rhoL/A............2

R is inversely proportional to A

As area increased R decreased

current flow more easily through a thick wire or
