    Study Notes

    Electric Dipole Moment

    • The SI unit for electric dipole moment is Coulomb-meter (C·m).

    Real Dipoles vs. Theoretical Definition

    • Real dipoles are different from the theoretical definition because they have a finite size, whereas theoretical dipoles are considered point dipoles.

    Debye (D)

    • Debye (D) is a unit of measurement for electric dipole moment, where 1 Debye is equivalent to 3.33564 × 10^-30 C·m.

    Point Charges and Electric Dipoles

    • Point charges are related to electric dipoles because two equal and opposite point charges separated by a small distance form an electric dipole.

    Direction of Electric Dipole Moment

    • The direction of the electric dipole moment for two point charges is from the negative charge to the positive charge.
