Answer:
The resistance of a wire is inversely proportional to the area of cross section of the wire. ... Hence, the resistance of wire decreases as the diameter of the wire increases and the resistance of the wire increases as the diameter of the wire decreases.
Factors resistivity depends on:
material, eg copper, has lower resistance than steel.
length - longer wires have greater resistance.
thickness - smaller diameter wires have greater resistance.
temperature - heating a wire increases its resistance.
Therefore length hai tera answer
