what is electric potential
Answers
Answer:
An electric potential is the amount of work needed to move a unit of charge from a reference point to a specific point inside the field without producing an acceleration. Typically, the reference point is the Earth or a point at infinity, although any point can be used.
➢ Electric Potential
- The scalar potential of the electrostatic field is called electric potential, or electrostatic potential .
In the electric field in a point charge of potential energy with it the amount of charge carried by the (positive and negative about the electric potential and the positive and negative charges are brought to the potential of point size is determined and the calculation of the positive and negative) ratio, The electric potential called this point is usually expressed by φ. Electric potential is a physical quantity that describes an electric field from an energy perspective. (The electric field strength describes the electric field from the perspective of force). The potential difference can generate current in a closed circuit (when the potential difference is quite large, insulators such as air can also become conductors). Electric potential is also called electric potential.
Expression
- φA = Ep / q
➢ Definition
In electrostatics , electric potential is defined as :
- The ratio of the electric potential energy of a unit charge at a certain position in the electric field to the amount of charge it carries.
The electric potential is only a magnitude, no direction, is a scalar , its value has no absolute meaning, only a relative meaning.
