Definition of zero potential

1 : **the ideal potential of a point infinitely distant from all electrification**. 2 : the actual potential of the surface of the earth taken as a point of reference — compare ground sense 7b.

If the electric dipole is initially perpendicular to the electric field,€=90°,cos90°=0 and then the above expression reduces to a compact form,**u= -PE cos£=-P.E.** When an electric dipole is placed in a uniform electric field with a angle of 90° or π/2, its potential energy is 0.

Therefore, the electric potential due to an electric dipole at a given point is equal to **KPcosθr2−a2cos2θ**.

Electric Potential of a Dipole

where r_{1} and r_{2} respectively are **distance of charge +q and -q from point R**. From above equation we can see that potential due to electric dipole is inversly proportional to r^{2} not 1/r which is the case for potential due to single charge.

In physics, chemistry and biology, a potential gradient is **the local rate of change of the potential with respect to displacement**, i.e. spatial derivative, or gradient. This quantity frequently occurs in equations of physical processes because it leads to some form of flux.

: **the vector that represents the rate at which a potential changes with position in a specified direction** specifically : the rate of change with height of the atmospheric electric potential.

Electric potential energy is a scalar quantity and possesses only magnitude and no direction. It is measured in terms of Joules and is denoted by V.

An electric dipole **deals with the separation of the positive and negative charges found in any electromagnetic system**. A simple example of this system is a pair of electric charges of equal magnitude but opposite sign separated by some typically small distance. (A permanent electric dipole is called an electret.)

For the dependency of electric potential (V) with distance (r) can be clearly seen by the given formula. Thus, **the electric dipole varies inversely to the square of a distance** ${{(r)}}$.

Bond dipole: **The partial charges assigned to bonded atoms due to differences in electron density caused by electronegativity, inductive effects, and other factors**. Indicated with δ^{+} and δ^{-} and/or the arrow symbol.

The electric potential due to a dipole at its equatorial point is **zero**.

The potential energy of the electron in the field of the positive proton point charge is **U(r) = -q _{e}V(r) = - k_{e}q_{e}^{2}/r**. The total energy is the sum of the electron's kinetic energy and its potential energy. KE(r) + PE(r) = -½k

A dipole is a pair of opposite charges with equal magnitudes separated by a distance, d. is the permittivity of free space. The electric potential is **a scalar field whose gradient becomes the electrostatic vector field**. Since it is a scalar field, it is easy to find the potential due to a system of charges.
