For wires of identical material but different thicknesses, connected to the same electrical supply, which wire offers easier flow of current? Support your answer with a reason.
A conductor's electrical resistivity is a measurement of its to the passage of an electric current. The electrical resistivity of a material is always and .
The conductor's resistance is proportional to its area of cross-section. So, the resistance will be wire and . Hence, the current flows more easily through a thicker wire than a thinner wire.
