A commonly used coaxial cable, RG-58, has a characteristic impedance of 50 ohms. If its length is doubled, its characteristic impedance will:

Question

Quizplus · Accepted Answer

The characteristic impedance of a coaxial cable, like RG-58, is determined by its physical construction (such as the diameter of the inner conductor and the dielectric constant of the insulating material between the conductors) and does not change with length.
