    en.wikipedia.org/wiki/Electrical_energy

    Electricity generation is the process of generating electrical energy from other forms of energy.. The fundamental principle of electricity generation was discovered during the 1820s and early 1830s by the British scientist Michael Faraday.

  3. Electric potential energy - Wikipedia

    en.wikipedia.org/wiki/Electric_potential_energy

    Electric potential energy is a potential energy (measured in joules) that results from conservative Coulomb forces and is associated with the configuration of a particular set of point charges within a defined system.

  4. Electric charge - Wikipedia

    en.wikipedia.org/wiki/Electric_charge

    Electric charge (symbol q, sometimes Q) is a physical property of matter that causes it to experience a force when placed in an electromagnetic field.Electric charge can be positive or negative.

  5. Chemical energy - Wikipedia

    en.wikipedia.org/wiki/Chemical_energy

    Chemical energy is the energy of chemical substances that is released when the substances undergo a chemical reaction and transform into other substances. Some examples of storage media of chemical energy include batteries, [1] food, and gasoline (as well as oxygen gas, which is of high chemical energy due to its relatively weak double bond [2] and indispensable for chemical-energy release in ...

    Energy (from Ancient Greek ἐνέργεια (enérgeia) 'activity') is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light.

  7. Eddy current - Wikipedia

    en.wikipedia.org/wiki/Eddy_current

    In electromagnetism, an eddy current (also called Foucault's current) is a loop of electric current induced within conductors by a changing magnetic field in the conductor according to Faraday's law of induction or by the relative motion of a conductor in a magnetic field.
