Therefore, when the length of a conductor is increased 3 times, its resistance becomes three times its original value, assuming the cross. Therefore we can say that when the length of the wire is tripled then resistance will also become three times ... That is, the cross. Solution Resistance, = where l = length of wire A = area of cross-section of the wire When the length is tripled, l' = 3l New resistance, . Note: The resistance of the wire is dependent on the length, the cross-sectional area, and the resistivity of the material of the wire. We. In the study of electricity and electronics, the resistance of a wire is influenced significantly by its length. This article.
Thus, the resistance gets tripled when the length of a conductor is increased three times. Hence, option (A) is correct.
