The word coaxial means same axis. So for a long straight cable to be coaxial, it must have concentric cylindrical shaped conductor around it. Coaxial cable (popularly called ‘coax’) has various applications ranging from current conductors to radiofrequen…

Textbook Question

Chapter 20, Problem 79GP

The effect of transmission lines. Two hikers are reading a compass under an overhead transmission line that is 5.50 m above tine ground and carries a current of 0.800 kA in a horizontal direction from north to south. (a) Find the magnitude and direction of the magnetic field at a point on the ground directly under line transmission line. (b) One hiker suggests Fiat they walk 50 m away from the lines to avoid inaccurate compass readings due to the current. Considering that the earth’s magnetic field is on the order of 0.5 × 10⁻⁴ T₁ is the current really a problem?

Paraxial design of a field flattener. Imagine your optical system has Petzal curvature of the field with radius p. In Module 1 of Course 1, a homework problem asked you to derive the paraxial focus shift along the axis when a slab of glass was inserted in a converging cone of rays. Find or re-derive that result, then use it to calculate the paraxial radius of curvature of a field flattener of refractive index n that will correct the observed Petzval. Assume that the side of the flattener facing the image plane is plano. What is the required radius of the plano-convex field flattener? (p written as rho )
