What is the charge of an electric dipole?

What is charge dipole moment?

The dipole moment (μ) is defined as the product of the magnitude of the charge, e, and the distance separating the positive and negative charges, l: μ = el. Electrical charge is measured in electrostatic units…

What is the net charge of a dipole?

From the dipole equation it follows that there exists electric field around dipole when charges are separated by distance, so there is flux through the surface which implies that there is charge enclosed in the surface (from gauss law). But net charge of dipole is said to be zero.

What is a neutral dipole?

An electric dipole is formed in a neutral system if the center of positive charge and the center of negative charge do not coincide. At the atomic scale, a molecule may have a permenant dipole moment if the electronic charge distribution is displaced with respect to the nuclear charge distribution.

What are the properties of electric dipoles?

Whether electric or magnetic, dipoles can be characterized by their dipole moment, a vector quantity. For the simple electric dipole, the electric dipole moment points from the negative charge towards the positive charge, and has a magnitude equal to the strength of each charge times the separation between the charges.

What is the direction of electric dipole moment?

The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge. Dipole moments tend to point along the direction of the surrounding electric field.

What is electric dipole moment and its SI unit?

Electric dipole moment is defined as the product of charge and the distance between the charges, and is directed from negative to positive charge. The SI unit of electric dipole moment is coulomb metre (Cm).
