A cylindrical conductor of uniform cross-section has resistivity p. The end-to- end separation is L and the cross-section end-face surface area is A. One end is at 10V and the other is at OV. a) Obtain an expression for the magnitude of the electrical field within the conductor. b) Obtain an expression for the current density vector within the conductor. c) Obtain an expression for the resistance between the two end-face of separation L. d) Suppose now that a segment of length L/3 is enlarged to twice its cross- section. What is the new expression for the resistance between the end- face of separation L. 10V @x=0 OV @x=L A cylindrical conductor of uniform cross-section has resistivity p.
