A coaxial air line has an inner conductor diameter of 2mm and the inner diameter of the outer conductor is 4.6mm. A voltage of 1 V is applied to the inner conductor.
(a) Determine the surface charge densities on the inner conductor and the inner surface of the outer conductor.
(b) What is the potential at a point midway between the conductors?
(c) What is the resistance of this coaxial line per meter at dc, assuming that the outer is 0.5mm thick, and both conductors are made of copper conductivity = 5:8 107 S/m.
(d) What is the capacitance per meter of this coaxial line?
(e) What is the impedance of this coaxial line?
