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