- 3) In above figure, current flows through a truncated circular cone of conductivity o = 10* (S/m). Left radius of the cone is a= 1 cm, right radius of the cone is b = 2 cm, and length of the cone is L = 0.2 m. The z-axis given in the figure is the rotation axis of the cone. a) Assume that this resistance is fed by DC voltage as shown in figure. Then, the electric field intensity E inside the conductor becomes only dependent on z variable but not p and/or o variable. For this DC case, what is DC resistance of this cone structure? b) Assume that DC voltage source is replaced with high frequency AC voltage source. For this case, in addition to dependency on z variable, the electric field intensity E inside the conductor is also directly proportional with p as being more realistic condition/model for high frequency AC circuits.
