The resistance of a conductor is directly proportional to:

Its area of cross-section density melting point length

length

Resistance of a material is defined as the property of a material by virtue of which it opposes the flow of electric current. \(\text{Resistance, R = }\frac{\rho l}{A}\), where, \(\rho\) is the resistivity, \(l\) is the length, and \(\text{A}\) is the area of cross-section.
