**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
