# Read the following informations. (i) Resistivity of copper is lower than that of aluminium which in turn is lower than that of constantan

(b) Wire E’has the minimum resistance, since it has least length, maximum thickness and least resistivity. [using $R = \rho ;\frac{l}{A}$]
© $R_{3}$ > $R_{5}$ > $R_{1}$ [using relation $R = \rho ;\frac{l}{A}$ and comparison ]
