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.
