Vedclass · Answer

(D) The resistance $R$ of a conductor is given by the formula $R = \rho \frac{L}{A}$,where $\rho$ is resistivity,$L$ is length,and $A$ is the cross-sectional area.$1$. As length $L$ increases,resistance $R$ increases.$2$. As cross-sectional area $A$ decreases,resistance $R$ increases.$3$. For a conductor,resistivity $\rho$ increases with an increase in temperature,which leads to an increase in resistance $R$.Therefore,all the given factors lead to an increase in resistance.
