Unbalanced line

This article is about the electrical transmission line. For the American football offensive line, see glossary of American football. For three-phase electric power lines carrying unbalanced currents see Three-phase electric power#Unbalanced loads.

In electrical engineering, an unbalanced line is a transmission line, often coaxial cable, whose conductors have unequal impedances with respect to ground; as opposed to a balanced line. Microstrip and single-wire lines are also unbalanced lines.
