A transmission line has aluminum conductors of a radius of 1.0 inches. If the aluminum conductors are replaced by steel conductors of an effective radius of 2.0 inches, the line:
O A. None of the choices are correct
O B. There is not enough information available to make any determination
O C. Inductance would increase
O D. Inductance would decrease but capacitance would increase
O E. Inductance would increase
Transmission line is a specialized cable or other structure designed to conduct
electromagnetic waves in a contained manner. The term applies when the
conductors are long enough that the wave nature of the transmission must be
considered.
