The image of electric dipole moment is shown above.
To compute for electric dipole moment, two essential parameters are needed and these parameters are Magnitude of Each Dipole (q) and Distance of Separation (d).
The formula for calculating electric dipole moment:
p = qd
Where:
p = Electric Dipole Moment
q = Magnitude of Each Dipole
d = Distance of Separation
Let’s solve an example;
Find the electric dipole moment when the magnitude of each dipole is 21 and the distance of seperation is 7.
This implies that;
q = Magnitude of Each Dipole = 21
d = Distance of Separation = 7
p = qd
p = (21)(7)
p = 147
Therefore, the electric dipole moment is 147 C-m.
Calculating the Magnitude of Each Dipole when the Electric Dipole Moment and the Distance of Separation is Given.
q = p / d
Where:
q = Magnitude of Each Dipole
p = Electric Dipole Moment
d = Distance of Separation
Let’s solve an example;
Given that, the electric dipole moment is 12 and the distance of seperation is 4. Find the magnitude of each dipole?
This implies that;
p = Electric Dipole Moment = 12
d = Distance of Separation = 4
q = p / d
q = 12 / 4
q = 3
Therefore, the magnitude of each dipole is 3.
