(i.) On what factors does resistivity of a conductor depend? (ii.)Will the current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why? (iii.) Let resistance of an electrical component remain constant while the potential difference across the ends of the component decreases to half of its former value. What change will occur in the current through it?

Answer:
The current will flow more easily through a thick wire than through a thin wire of the same material when connected to the same source. ... A thick wire has a greater diameter and hence lesser resistance making the current to flow through it more easily.
