Detailed Solution

When a normal resistance wire is replaced with another thicker wire of the same length and material, the current flow will increase, and the resistance will decrease.
We know the resistance of a metallic wire is directly proportional to the length and inversely proportional to the area of the cross-section.

R α \frac{l}{A}

. Here the area of the cross-section of the wire is more. Hence the resistance will decrease. Using Ohm’s law, resistance is inversely proportional to the current flowing in the wire. Therefore, when the resistance decreases, the current increases.
