Introduction
An electric potential is also called a volt in the term of
electrical engineering. ’’It is an amount of work which is needed to move a
unit or a charge from one place to a specific place without any kind of
acceleration’’.
Explanation
According to electrostatics, electric potential is a scalar
quantity and is denoted by V. It is equal to a charge particle at any location
or a place and is divided by the charge of that particle which is measured in
coulombs. By division an answer remained which is the property of electric
potential.
The value of electric potential is measured in a static and
dynamic electric field at a time in units of volt. The electric potential is
assumed zero at infinity.
Formula of electric potential
The electric potential is created by a charge Q at a
distance of r from the charge. The formula is given below:
where ε0 is the dielectric constant.This is known as
the coulomds potential.
The electric potential of
point charges is equal to the sum of point charges.This method simplifies in calculations
easily.
Units
The SI unit of electric potential
is volt and is denoted by VE. This is because of the difference of electric
potential between two points which are known as volt. The older units of electric potential
are also using these days which includes ab volt and stat volt.
