Resistance (R) is inversely proportional to the area of cross-section (A) of the wire. So, thicker the wire, lower is the resistance of the wire and vice-versa. Therefore, current can flow more easily through a thick wire than a thin wire. 𝑅=𝜌𝐿/𝐴 ⇒𝑅 ∝1 /𝐴

Will current flow more easily through a thick wire or a thin wire of the same material, when connected to the same source? Why?
Resistance (R) is inversely proportional to the area of cross-section (A) of the wire. So, thicker the wire, lower is the resistance of the wire and vice-versa. Therefore, current can flow more easily through a thick wire than a thin wire. 𝑅=𝜌𝐿/𝐴 ⇒𝑅 ∝1 /𝐴
