The following table gives the lenght of three copper wires, their diameters, and the applied potential difference across their ends. Arrange the wires in increasing order according to the following:
(a) The mangnitude of the electric field within them,
(b) The drift speed ofd electrons through them, and
(c) The current density within them.
wire no. Length Diameter Potential Difference
1 L 3d V
2 2L d V
3 3L 2d 2V
