Explanation:
The resistance of wire depends on three factors
1.length of the conductor
2. Area of the conductor
3. Nature of the type of material
R=рl/A
if area increases then resistance decreases (as inversely proportional)
the Area of the wire A= (pi)*r*r (where r is radius of the wire)
if R doubles then area becomes 4 times…then then the resistance becomes (1/4th) of the previous resistance
R2=R1/4
