Coulomb's law or Coulomb's inverse-square law is a law of physics describing the electrostatic interaction between electrically charged particles.

An electric field is the region of space surrounding electrically charged particles and time-varying magnetic fields.

In physics, Gauss's law, also known as Gauss's flux theorem, is a law relating the distribution of electric charge to the resulting electric field.

The electric potential at a point is equal to the electric potential energy of a charged particle at that location divided by the charge of the particle.

Capacitance is the ability of a body to store an electrical charge and a dielectric is an electrical insulator that can be polarized by an applied electric field.

Electric current is a flow of electric charge through a medium and electrical resistance of an electrical element is the opposition to the passage of an electric current through that element

A DC circuit (Direct Current circuit) is an electrical circuit that consists of any combination of constant voltage sources, constant current sources, and resistors.

A magnetic field may be represented by a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field.

In classical electromagnetism, Ampère's circuital law, discovered by André-Marie Ampère in 1826,relates the integrated magnetic field around a closed loop to the electric current passing through the loop.

Faraday's law of induction dates from the 1830s, and is a basic law of electromagnetism relating to the operating principles of transformers, inductors, and many types of electrical motors and generators.

In electromagnetism and electronics, inductance is that property of a circuit by which a change in current in the circuit “induces” a voltage (electromotive force) in both the circuit itself (self-inductance) and any nearby circuits (mutual inductance).
