### ELECTRIC DIPOLE NOTES: ELECTRIC DIPOLE , DIPOLE LENGTH, ELECTRIC FIELD DUE TO ELECTRIC DIPOLE

Electric Dipole: It is a  system of equal and opposite charges separated by some  fixed distance.

DIPOLE LENGTH: the distance AB = 2a is called dipole length. It is a vector quantity , whose direction is from -q to +q.

Dipole Moment (𝑷⃗  ): It is the measure of strength of electric field produced by a dipole It is defined as the product of magnitude of either charge and separation between the charges.

i.e. 𝐏⃗ = q × 𝟐𝒂⃗  By convention, direction of electric dipole moment is always taken from negative to positive charge.

Units of 𝑷⃗  : units of 𝑷⃗  = units of charge × units of distance = Cm

Dimensions of  𝐏⃗  : [𝑷⃗ ] = [q] × [2a] = AT × L = LTA
