Coulomb-meter (C⋅m)

The standard unit of measurement for electric dipole moment, representing the separation of positive and negative charges.

Electric Dipole

A pair of equal but opposite charges, placed incredibly close together. Think of them as a tiny battery!

Distance 's' in a Dipole

The distance between each charge and the center point of the dipole, often represented with the letter 's'.

Debye (D)

A unit of measurement for electric dipole moment often used in atomic physics and chemistry.

Study Notes

Electric Dipole Moment

The SI unit for electric dipole moment is Coulomb-meter (C·m).
Two equal and opposite charges that are infinitesimally close together are defined as an electric dipole.
The distance between either charge and the center of the dipole is often denoted by the symbol 'l' or 'd'.
The debye (D) unit of measurement is used in the field of chemistry, particularly in the study of molecular polarity.
The electric dipole moment measures the separation of positive and negative electric charges within a system, such as a molecule.
