  2. Electrostatics - Wikipedia

    en.wikipedia.org/wiki/Electrostatics

    On a conductor, a surface charge will experience a force in the presence of an electric field. This force is the average of the discontinuous electric field at the surface charge. This average in terms of the field just outside the surface amounts to: =,

  3. Electricity - Wikipedia

    en.wikipedia.org/wiki/Electricity

    The electric field was formally defined as the force exerted per unit charge, but the concept of potential allows for a more useful and equivalent definition: the electric field is the local gradient of the electric potential. Usually expressed in volts per metre, the vector direction of the field is the line of greatest slope of potential, and ...

  4. Electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Electromagnetism

    The electromagnetic force is responsible for many of the chemical and physical phenomena observed in daily life. The electrostatic attraction between atomic nuclei and their electrons holds atoms together. Electric forces also allow different atoms to combine into molecules, including the macromolecules such as proteins that form the basis of life.

  5. Electric field - Wikipedia

    en.wikipedia.org/wiki/Electric_field

    An electric field (sometimes called E-field [1]) is the physical field that surrounds electrically charged particles.Charged particles exert attractive forces on each other when their charges are opposite, and repulse each other when their charges are the same.

  6. Fundamental interaction - Wikipedia

    en.wikipedia.org/wiki/Fundamental_interaction

    The gravitational and electromagnetic interactions produce long-range forces whose effects can be seen directly in everyday life. The strong and weak interactions produce forces at subatomic scales and govern nuclear interactions inside atoms. Some scientists hypothesize that a fifth force might exist, but these hypotheses remain speculative.

  7. Introduction to electromagnetism - Wikipedia

    en.wikipedia.org/wiki/Introduction_to...

    Electric charges produce a vector field called the electric field. The numerical value of the electric field, also called the electric field strength, determines the strength of the electric force that a charged particle will feel in the field and the direction of the field determines which direction the force will be in.

  8. List of electrical phenomena - Wikipedia

    en.wikipedia.org/wiki/List_of_electrical_phenomena

    Electric shock — Physiological reaction of a biological organism to the passage of electric current through its body. Ferranti effect — A rise in the amplitude of the AC voltage at the receiving end of a transmission line , compared with the sending-end voltage, due to the capacitance between the conductors, when the receiving end is open ...

  9. Static electricity - Wikipedia

    en.wikipedia.org/wiki/Static_electricity

    Static electricity is an imbalance of electric charges within or on the surface of a material. The charge remains until it can move away by an electric current or electrical discharge. The word "static" is used to differentiate it from current electricity, where an electric charge flows through an electrical conductor. [1]
