  2. Faraday's laws of electrolysis - Wikipedia

    en.wikipedia.org/wiki/Faraday's_laws_of_electrolysis

    Faraday discovered that when the same amount of electric current is passed through different electrolytes connected in series, the masses of the substances deposited or liberated at the electrodes are directly proportional to their respective chemical equivalent/equivalent weight (E). [3]

  3. List of physical quantities - Wikipedia

    en.wikipedia.org/wiki/List_of_physical_quantities

    Measure for how easily current flows through a material siemens (S = Ω −1) L −2 M −1 T 3 I 2: scalar Electrical conductivity: σ: Measure of a material's ability to conduct an electric current S/m L −3 M −1 T 3 I 2: scalar Electric potential: φ: Energy required to move a unit charge through an electric field from a reference point ...

  4. Energy density - Wikipedia

    en.wikipedia.org/wiki/Energy_density

    The density of thermal energy contained in the core of a light-water reactor (pressurized water reactor (PWR) or boiling water reactor (BWR)) of typically 1 GW (1000 MW electrical corresponding to ≈ 3000 MW thermal) is in the range of 10 to 100 MW of thermal energy per cubic meter of cooling water depending on the location considered in the ...

  5. Mathematical formulation of the Standard Model - Wikipedia

    en.wikipedia.org/wiki/Mathematical_formulation...

    The pattern of weak isospin T 3, weak hypercharge Y W, and color charge of all known elementary particles, rotated by the weak mixing angle to show electric charge Q, roughly along the vertical. The neutral Higgs field (gray square) breaks the electroweak symmetry and interacts with other particles to give them mass.

  6. Properties of water - Wikipedia

    en.wikipedia.org/wiki/Properties_of_water

    Water (H 2 O) is a polar inorganic compound that is at room temperature a tasteless and odorless liquid, which is nearly colorless apart from an inherent hint of blue.It is by far the most studied chemical compound [20] and is described as the "universal solvent" [21] and the "solvent of life". [22]

  7. Electric current - Wikipedia

    en.wikipedia.org/wiki/Electric_current

    The ampere is an SI base unit and electric current is a base quantity in the International System of Quantities (ISQ). [4]: 15 Electric current is also known as amperage and is measured using a device called an ammeter. [2]: 788 Electric currents create magnetic fields, which are used in motors, generators, inductors, and transformers.

  8. Continuity equation - Wikipedia

    en.wikipedia.org/wiki/Continuity_equation

    For example, if in the mass continuity equation for flowing water, u is the water's velocity at each point, and ρ is the water's density at each point, then j would be the mass flux, also known as the material discharge. In a well-known example, the flux of electric charge is the electric current density.

  9. Hydraulic analogy - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_analogy

    The mass of the rotor and the surface area of the vanes restricts the water's ability to rapidly change its rate of flow (current) through the pump due to the effects of inertia, but, given time, a constant flowing stream will pass mostly unimpeded through the pump, as the rotor turns at the same speed as the water flow. The mass of the rotor ...
