Which two wire properties would provide the greatest resistance to the flow of a current? long, thin hot, thick cool, thick

The quantity that measures reduce in electric current flow through the material is said to be resistance. The formula to determine the resistance is:

where R is resistance, is resistivity, L is length of the wire, and A is cross sectional are.

From the above formula it is clear that the resistance is dependent on material of the substance, length of the wire, and its cross sectional area  i.e. the resistance is directly proportional to length of the wire and inversely proportional to the cross sectional area of the wire.

Hence, two wire properties that would provide the greatest resistance to the flow of a current are long and thin.
