The voltage-current variations of two metallic wire X and Y at constant temperature is shown in fig Assumign that the wires have the same length and the same diameter, explain which of the two wires will have larger resisitivity.

Text Solution

Verified by Experts

`R = (rhol)/(A), "so " rho prop R. "But" R_Y gt R_X.`
Because for same V, current in Y is less. So `rho_y gt rho_x.`
