Coulomb’s law, electric field and potential

In electrostatics, the ideas of electric field and electric potential are critical. The link between an electric field and its potential is similar to that between a gravitational field and its potential, where the potential is a feature of the field that expresses the field’s effect on an item or a body. Furthermore, the electric […]

The area around the electric charge in which the electric force or stress is present is known as the electric field. It depends on the magnitude; if the magnitude of the charge is high then it will create a huge amount of stress on the region. E represents the electric field. The SI unit of

Electric charges are present widely in our everyday life. For example, whenever we rub a nylon cloth against some other fabric or our skin, we can feel the static electricity formed. An object having equal and opposite charges separated by distance ‘d’ is termed an electric dipole with charges. The midpoint between these two charges

As we already know, an electric dipole is a system of two point charges +q and -q that are opposite and equal charges separated by a small distance of 2a. The electric dipole moment is represented by a vector p of magnitude 2qa, which points in the direction of -q to +q. The electric potential

An electric dipole is a separation of electrical charges that are opposite. Its quantification can be done by its dipole moment (μ). The occurrence of an electric dipole takes place when positive and negative charges are separate from each other. A good example here can be a proton and an electron. This can be very

As we know the concept of the electric field, let us now see what a dipole is. Because a dipole electric field is made up of two equal but opposite ions, the net charge will be null. When analysing electric dipoles, it’s important to remember that just because an electric dipole’s overall charge is nil

The electric charge is defined as the property of the matter that is due to its subatomic particles. It causes the material to experience a force when placed in a magnetic and electric field. The electric charge is a scalar quantity. It has both magnitude and direction but is an exception to the general vector

The most basic way to define an electric field would be as the electric force per unit charge. The direction of the field is considered to be the direction of the force exerted by it on a positive test charge. The field is radially outward from a charge that is positive. On the other hand,

Generally speaking, materials that are classified as dielectrics are those that conduct electricity with low efficiency. When an electric field is supplied to a dielectric material, it can be easily polarised. Applied electric fields can polarise dielectrics (also known as dielectric materials or dielectric media) in electromagnetism. Electric charges do not flow through a dielectric

Dielectrics are materials that become polarised when subjected to an electric field. Due to the action of the external electric field, the charges in the molecules move apart from each other, reducing the strength of the electric field in that medium. We have free electrons in metals. When a conductor is held in an external
