A conductor is made of an isotropic material resistivity p has rectangular cross section Horizontal dimension of the rectangle decreases linearly from 2x at one end to x at the other end and vertical dimension increases from y to 2y as shown in figure Length of the conduction along the axis is equal to l A battery is connected across this conduction between the two rectangular faces Then 2 2y A resistance of the conductor is equal t50 pl 2xy B rate of generation of heat per unit length is maximum at middle cross section C drift velocity of conduction electrons is minimum at middle section
