Electric potential is defined as the amount of work required to move a unit charge from a reference point to a particular point against the electric field. When a body moves against the electric field, it gains a certain amount of energy, called the electric potential. The electrical potential of the charge is produced by […]

The electric potential is a metric for how much energy is stored per unit of charge. Electric potential energy is the amount of energy gained when an object moves against an electric field. For each charge, the electric potential is determined by dividing the potential energy by the charge quantity. For a uniform field, the

Introduction An electric dipole is a pair of equal and opposite electric charges with non-coinciding centers.  Electric dipole that is induced in an atom, in which the centre of the negative cloud of electrons has been displaced slightly away from the nucleus by an external electric field.  The atom  loses its dipolarity in the situation

Eigenvalues and Eigenvectors are used in linear algebra in mathematics, but in physics, these are widely used for vibration analysis, simple harmonic oscillators, quantum mechanics, matrix diagonalisation, and atomic orbitals. In particular, molecular physics uses Eigenvalues as ionisation potentials.  The physical system has a wave function. Schrodinger’s equation is the solution to obtain the specific

A solid body has tightly packed atoms that won’t move from one position to another like fluids. However, some solids exhibit elastic properties, which means that their dimensions can be changed by applying force. Once the deforming forces are withdrawn, the body will return to its shape. Elasticity plays a significant role in mechanical physics,

Potential difference is the key to how current flows. Definition of electric potential says that the amount of work is needed to bring a positive unit charge from infinity. If there is a difference between the potential of two points, a potential gradient is generated.   What is the potential difference? Potential difference can be defined

Electromotive force is present in various electrical device cells, batteries, etc. This force does not operate like the ordinary force that we have learnt in mechanics. Inside an electrical device, different forms of energy like chemical energy in the case of batteries or mechanical energy in the case of a generator get converted to electrical

Potential is an essential concept of mechanics. It can be defined for any force field like a gravitational field, electrostatic field, etc. In this note of the Dimension formula for Electric Potential, we will discuss Potential for the electrostatic field. Electric Potential is nothing but the work required to bring a charged particle from infinity

A dielectric material is the non-metallic material having a high specific resistivity, a negative resistance temperature coefficient and with large resistance of insulation. Dielectric A dielectric is a substance that becomes polarized when exposed to an electric field. The charges present in the molecules move away from each other due to the action of the

Point charges, similar to electrons, are among the key construction squares of issue. Additionally, round charge movements (like charge on a metal circle) make external electric fields definitively like a point charge. The electric potential on account of a point charge is, henceforth, a case we need to consider. We can use math to notice
