  2. Bethe formula - Wikipedia

    en.wikipedia.org/wiki/Bethe_formula

    At low energy, the energy loss according to the Bethe formula therefore decreases approximately as v −2 with increasing energy. It reaches a minimum for approximately E = 3Mc 2, where M is the mass of the particle (for protons, this would be about at 3000 MeV).

  3. Losses in electrical systems - Wikipedia

    en.wikipedia.org/wiki/Losses_in_electrical_systems

    In an electrical or electronic circuit or power system part of the energy in play is dissipated by unwanted effects, including energy lost by unwanted heating of resistive components (electricity is also used for the intention of heating, which is not a loss), the effect of parasitic elements (resistance, capacitance, and inductance), skin effect, losses in the windings and cores of ...

  4. Dielectric loss - Wikipedia

    en.wikipedia.org/wiki/Dielectric_loss

    The loss tangent is then defined as the ratio (or angle in a complex plane) of the lossy reaction to the electric field E in the curl equation to the lossless reaction: tan ⁡ δ = ω ε ″ + σ ω ε ′ . {\displaystyle \tan \delta ={\frac {\omega \varepsilon ''+\sigma }{\omega \varepsilon '}}.}

  5. Decay energy - Wikipedia

    en.wikipedia.org/wiki/Decay_energy

    The decay energy is the mass difference Δm between the parent and the daughter atom and particles. It is equal to the energy of radiation E . If A is the radioactive activity , i.e. the number of transforming atoms per time, M the molar mass, then the radiation power P is:

  6. Energy conversion efficiency - Wikipedia

    en.wikipedia.org/wiki/Energy_conversion_efficiency

    Energy conversion efficiency depends on the usefulness of the output. All or part of the heat produced from burning a fuel may become rejected waste heat if, for example, work is the desired output from a thermodynamic cycle. Energy converter is an example of an energy transformation.

  7. Q factor - Wikipedia

    en.wikipedia.org/wiki/Q_factor

    The Q factor is a parameter that describes the resonance behavior of an underdamped harmonic oscillator (resonator). Sinusoidally driven resonators having higher Q factors resonate with greater amplitudes (at the resonant frequency) but have a smaller range of frequencies around that frequency for which they resonate; the range of frequencies for which the oscillator resonates is called the ...

  8. Faraday efficiency - Wikipedia

    en.wikipedia.org/wiki/Faraday_efficiency

    Faradaic loss is only one form of energy loss in an electrochemical system. Another is overpotential , the difference between the theoretical and actual electrode voltages needed to drive the reaction at the desired rate.

  9. Electron energy loss spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Electron_energy_loss...

    Electron energy loss spectroscopy (EELS) is a form of electron microscopy in which a material is exposed to a beam of electrons with a known, narrow range of kinetic energies. Some of the electrons will undergo inelastic scattering, which means that they lose energy and have their paths slightly and randomly deflected. The amount of energy loss ...
