Common questions
What is the Electric Dipole Moment formula?
Electric Dipole Moment is written p = qd. Electric dipole moment for two equal and opposite charges. It belongs to Electricity & Magnetism, under Electrostatics.
What are the units in p = qd?
In SI units, p is dipole moment, measured in A·s·m; q is charge, measured in A·s; d is separation, measured in m.
How is the Electric Dipole Moment formula derived?
Defined as p = qd, pointing from negative to positive charge. The result is p = qd.
