b) A twin wire transmission line has a conductor radius a = 2mm and a spacing of D = 50 mm. A charge of λ = +40nC/m is deposited on one conductor, with the other conductor grounded. The line sits in free space. (i) Calculate the low frequency inductance per unit length. (ii) What is the characteristic impedance Zo of this line at high frequencies? (iii) Suggest two ways of reducing Zo without reducing the rated voltage of the twin wire line. Explain your reasoning
