Question 2

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

Answer

R = ρ lA\dfrac{l}{A}

Area of the cross-section of wire is inversely proportional to the resistance, so, the thick wire offers less resistance, hence, current will flow more easily through it.
