Electrostatics

Electrostatics is a branch of physics which is concerned with the study of electromagnetic phenomena in which electric charges are at rest, that is when there are no moving charges after static equilibrium is established. In physics, the electrostatic phenomenon refers to the properties of slow-moving or static electrical charges. The study of stationary electrical […]

Electrostatic forces between particles are attracting or repulsive forces induced by their electric charges. The Coulomb force, also known as the Coulomb interaction, was named after French physicist Charles-Augustin de Coulomb, who first characterised it in 1785.  Electrostatic phenomena can range from the simple attraction of plastic wrap to one’s palm after it has been

Electrons are subatomic particles with a negative charge of about 1.602 × 10-19. The charge is equal in magnitude to that of the positive charge on a proton but has an opposite sign.  An electron under an electrical field feels a repulsive or attractive force. When a positive electrical field is applied to the metal,

Before knowing who was the first to come up with the idea of finding an electron in an orbital and how to find them, one must first understand what orbitals are. An orbital is an energy level into which electrons can arrange themselves.  Electrons have a negative charge because they tend to occupy the available

Electrons were discovered as a result of a study of cathode rays by JJ Thomson. It carries a negative charge ( 1.6 X 10-19 C). The name electricity is taken from the Greek word electron, meaning amber. Many pairs of materials which on rubbing could attract light objects like straw, pith balls, and bits of

An electric field is said to be a property that exists in the space where any charge is present. Another term that can be used to describe electric fields is force per unit charge. The formula to calculate the electric field is: E=F/Q where, F is considered to be the electrostatic force and Q be

When matter is held in an electric or magnetic field, it has a physical property called electric charge that governs it to experience a force. An electric charge is created by an electric field, whereas moving electric charges create a magnetic field. The electromagnetic force is created by the interactions of electric and magnetic fields.

Every charge produces its own electric field, and other charges experience the electric force in the vicinity of that charge. This force could be either attractive or repulsive, depending on the nature of the charges. We cannot ‘see’ electric fields with our naked eyes. These electric fields can be pictorially represented by the ‘electric lines

Electric flux is the measure of number of electric field lines passing through a given area. The electric flux is determined by the number of electric field lines travelling through a virtual surface.  It’s worth noting that while charges outside the closed surface have no effect on the electric flux, charges outside the closed surface

What is a Point Charge? A point charge is an entity or physical object with a certain imbalance in the number of electrons and protons, which gives it a positive or negative charge.  Depending upon the positive or negative charge induced on the point object, electric field lines will form. These lines will generate an
