     Consider the two-wire transmission line whose cross section is illustrated in Figure 7.34. Each wire is of radius 2 cm, and the wires are separated 10 cm. The wire centered at (0, 0) carries a current of 5 A while the other centered at (10 cm, 0) carries the return current. Find H at (5 cm, 0)  (10 cm, 5 cm) 
  
  Solution
a) H = H1 - H2
= I/4*Pi (1/5 - 1/5) = 0
b) H = H1 - H2
= I/4*pi ( 1/5 - 1/sqrt(125)
I = 5 ampere
H = 1.14
