## Difference between electric potential and electric potential energy

Electric potential: “Electric potential at a point in electric field is the amount of work done to bring the unit positive charge from infinity to that point.” The gravitational potential at point in the gravitational field is the gravitational potential energy of a unit mass placed at that point.In this way ,the electric potential at any point in the electric ...

## Discuss analogies and the differences between Coulomb’s law and the Biot- Savart’s law?

Similarities: Both the electric and magnetic field depends inversely on square of distance between the source and field point. Both electric field and magnetic field are proportional to the source strength namely charge and current element respectively. Both obey superposition principle. Differences: According to Coulomb’s law,the electrostatic force between two point charges is directly proportional to the product of their ...

## Electric flux:formula ,examples,problem & solutions

What is Electric Flux? “Total number of field lines passing through a certain element of area is called flux”. It may also be defined as “The scalar product of electric field intensity E and vector area  A“. Electric flux formula It is denoted by Greek letter Φ. Φ=E.A Φ=EAcosθ Where θ is the angle between E and A.Electric flux is a scalar quantity. ...
