21-11 Electric Dipoles. An electric dipole consists of two charges Q, equal in magnitude and opposite in sign, separated by a distance . The. dipole moment, p = Q , points from the negative to the positive charge.
electric dipole. The simplest molecular dipole consists of a pair of opposite, unit electric charges (of magnitude +q and -4) separated by a vector distance S; in this case, the molecular dipole moment m (which is an intensive property) is given as m = qs and has units of C m. For a complex protein molecule, such as that illustrated
ELECTRIC DIPOLES. In these notes, I write down the electric field of a dipole, and also the net force and the torque on a dipole in the electric field of other charges.
An electric dipole is a +Q and a Q separated by a vector a Very common system, e.g. in atoms and molecules The electric dipole moment is p= Qa pointing from Q to +Q

On the atomic and sub-atomic scale, the magnetic and electric dipole moments reveal structural information about the systems. On a much larger scale, dipole antennae are important in radio transmission and reception. In this module, we will discuss one of the two types of dipoles, the electric dipole.
This creates two centers of equal and opposite charges—what is called a dipole, as illustrated in Figure 18.25. The magnitude of the dipole is called the dipole moment. These two centers of charge will terminate some of the electric field lines coming from a free charge, as on a DNA molecule.
