Can someone explain where r = d/2cos(a) comes from? also why H=I/pi*d cos^2(a) instead of just cos(a) Find the total field H at a point P, in the 2 wire transmission line if d-80 cm, α-300, and 100A, and the field halfway between the wires. 11 out r H2 in 21 cos α 2tr Resultant H at P-H, cosa+H,cosα 2π r 2Tr But 11,1-1121 H-L cosa
