Define electric potential and potential difference.
Answers
Answer:
Define: The electrical potential is defined as the capability of the charged body to do work. When the body is charged, either electric electrons are supplied to it, or they are removed from it. In both the cases, the work is done. This work is stored in the body in the form of electric potential. Thus, the body can do the work by exerting a force of attraction or repulsion on the other charged particles.
Electric Potential Difference:
The electrical potential difference is defined as the amount of work done to carrying a unit charge from one point to another in an electric field. In other words, the potential difference is defined as the difference in the electric potential of the two charged bodies. When a body is charged to a different electric potential as compared to the other charged body, the two bodies are said to a potential difference. Both the bodies are under stress and strain and try to attain minimum potential
Unit: The unit of potential difference is volt.
What is Electric Potential?
Electric potential (V) is the property of points in space. Electric potential can be defined in several ways:
The value of the electric potential at a point in space numerically gives the amount of work that needs to be done to bring a unit positive charge from infinity to that point.
A charge q is said to have a potential energy of Vq if it is at a point in space which has a potential of V.
For example, if you place a charge q at a point, space nearby will have a non-zero value of potential. The electric potential at a point due to a charge at a distance r from it is given by:
V=kqr
What is Electric Potential Energy?
Electric potential energy (U) is the property of a system. Two charges in the vicinity of each other are said to have potential energy.
The electric potential energy associated with two charges separated by a distance r is given by:
U=kq1q2r
