Extracted text: The impedance of coaxial cable is given by the formula: 1 -In Ho Z cable = Here, b is the radius of the sheath and a is the radius of the core. (a) Does this formula give the impedance per unit length or the impedance of the entire cable? (b) If the dielectric has ɛ, = 1.3 and the core radius is a = 0.4 mm obtain a values for b that will lead to an impedance of 50 2. %3D
