Electric Potential

Science > Physics > Electrostatics > Electric Potential Electric Potential at a Point: The electric potential at any point in the electric field is defined as the work that must be done by the external force to move unit positive charge from infinity to that point without acceleration. If W is the work done in […]

No Comments on The Concept of Electric Field

Science > Physics > Electrostatics > The Concept of Electric Field When a charge is kept in a medium it sets around it, what is called an electric field. It can be represented by drawing what is called lines of force. If another charge is brought into this region it experiences a force. Due to the field, the […]

Dielectrics

Science > Physics > Electrostatics > Dielectrics In this article, we shall study dielectric materials (dielectrics), their working and types. Dielectrics are non-conducting substances. In these materials, free-moving electrons are not present. Thus there is no question of the movement of charge. When the dielectric material is kept in an external electric field, a dipole […]
