Electric potential (also called the electric field potential, potential drop, the electrostatic potential) is defined as the amount of work/energy needed per unit of electric charge to move the charge from a reference point to a specific point in an electric field.
An electric field (sometimes called E-field [1]) is a physical field that surrounds electrically charged particles.In classical electromagnetism, the electric field of a single charge (or group of charges) describes their capacity to exert attractive or repulsive forces on another charged object.
The electric dipole moment is a measure of the separation of positive and negative electrical charges within a system: that is, a measure of the system's overall polarity. ...
Coulomb's inverse-square law, or simply Coulomb's law, is an experimental law [1] of physics that calculates the amount of force between two electrically charged particles at rest.
Robert A. Millikan in 1891. Starting in 1908, while a professor at the University of Chicago, Millikan, with the significant input of Fletcher, [8] the "able assistance of Mr. J. Yinbong Lee", and after improving his setup, published his seminal study in 1913. [9]
In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines field theory and the principle of relativity with ideas behind quantum mechanics.
Aluminium–air batteries (Al–air batteries) produce electricity from the reaction of oxygen in the air with aluminium.They have one of the highest energy densities of all batteries, but they are not widely used because of problems with high anode cost and byproduct removal when using traditional electrolytes.
In physics, Gauss's law for magnetism is one of the four Maxwell's equations that underlie classical electrodynamics.It states that the magnetic field B has divergence equal to zero, [1] in other words, that it is a solenoidal vector field.
