- Physics, Electricity. a pair of electric point charges or magnetic poles of equal magnitude and opposite signs, separated by an infinitesimal distance.
- Physical Chemistry. a polar molecule.
- Also called dipole antenna. Radio, Television. an antenna of a transmitter or receiving set consisting of two equal rods extending in opposite direction from the connection to the lead-in wire.
- two electric charges or magnetic poles that have equal magnitudes but opposite signs and are separated by a small distance
- a molecule in which the centre of positive charge does not coincide with the centre of negative charge
- Also called: dipole aerial a directional radio or television aerial consisting of two equal lengths of metal wire or rods, with a connecting wire fixed between them in the form of a T
- A pair of electric charges or magnetic poles, of equal magnitude but of opposite sign or polarity, separated by a small distance.
- A molecule having two such charges or poles.
- An antenna consisting of two rods of equal length extending outward in a straight line. Dipole antennas are usually used for frequencies below 30 megahertz.
