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

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?

Solution:

Current will flow more easily through a thick wire because the resistance is inversely proportional to the area of cross-section of the wire. Which means when the area of cross section of the wire increases then resistance decreases or vice versa.
