  2. Electric potential energy - Wikipedia

    en.wikipedia.org/wiki/Electric_potential_energy

    The electric potential energy of a system of point charges is defined as the work required to assemble this system of charges by bringing them close together, as in the system from an infinite distance.

  3. Electric potential - Wikipedia

    en.wikipedia.org/wiki/Electric_potential

    The electric potential and the magnetic vector potential together form a four-vector, so that the two kinds of potential are mixed under Lorentz transformations. Practically, the electric potential is a continuous function in all space, because a spatial derivative of a discontinuous electric potential yields an electric field of impossibly ...

  4. Orders of magnitude (power) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(power)

    For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower. Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.

  5. Electrical energy - Wikipedia

    en.wikipedia.org/wiki/Electrical_energy

    Electrical energy is energy related to forces on electrically charged particles and the movement of those particles (often electrons in wires, but not always). This energy is supplied by the combination of current and electric potential (often referred to as voltage because electric potential is measured in volts) that is delivered by a circuit (e.g., provided by an electric power utility).

[210] Such an impact occurs every ~500,000 years. [211] 2.4×10 20 J Total latent heat energy released by Hurricane Katrina [212] 5×10 20 J

  7. Capacity of a set - Wikipedia

    en.wikipedia.org/wiki/Capacity_of_a_set

    More precisely, it is the capacitance of the set: the total charge a set can hold while maintaining a given potential energy. The potential energy is computed with respect to an idealized ground at infinity for the harmonic or Newtonian capacity , and with respect to a surface for the condenser capacity .

  8. Units of energy - Wikipedia

    en.wikipedia.org/wiki/Units_of_energy

    In physics and chemistry, it is common to measure energy on the atomic scale in the non-SI, but convenient, units electronvolts (eV). 1 eV is equivalent to the kinetic energy acquired by an electron in passing through a potential difference of 1 volt in a vacuum. It is common to use the SI magnitude prefixes (e.g. milli-, mega- etc) with ...

  9. Mass-to-charge ratio - Wikipedia

    en.wikipedia.org/wiki/Mass-to-charge_ratio

    When charged particles move in electric and magnetic fields the following two laws apply: Lorentz force law: = (+),; Newton's second law of motion: = =; where F is the force applied to the ion, m is the mass of the particle, a is the acceleration, Q is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.
