The flow of electric current in a conductor is opposed by the resistance of the conductor.
The resistance of the conductor is directly proportional to the length of the conductor
andinverselyproportionaltoitscross-section(thickness).Theresistanceintheconduc-
torproducesundesirableeffectsofvoltagedropandheating.Thus,thickerandshorter
conductors are desirable.
