  2. Electrophysiology - Wikipedia

    en.wikipedia.org/wiki/Electrophysiology

    Electrophysiology (from Greek ἥλεκτ, ēlektron, "amber" [see the etymology of "electron"]; φύσις, physis, "nature, origin"; and -λογία, -logia) is the branch of physiology that studies the electrical properties of biological cells and tissues.

  3. Transmission line - Wikipedia

    en.wikipedia.org/wiki/Transmission_line

    Transmission lines are used as pulse generators. By charging the transmission line and then discharging it into a resistive load, a rectangular pulse equal in length to twice the electrical length of the line can be obtained, although with half the voltage.

  4. Electrical load - Wikipedia

    en.wikipedia.org/wiki/Electrical_load

    An electrical load is an electrical component or portion of a circuit that consumes (active) electric power, [1] [2] such as electrical appliances and lights inside the home. The term may also refer to the power consumed by a circuit. This is opposed to a power supply source, such as a battery or generator, which provides power. [2]

  5. Developmental bioelectricity - Wikipedia

    en.wikipedia.org/wiki/Developmental_bioelectricity

    Developmental bioelectricity is a sub-discipline of biology, related to, but distinct from, neurophysiology and bioelectromagnetics.Developmental bioelectricity refers to the endogenous ion fluxes, transmembrane and transepithelial voltage gradients, and electric currents and fields produced and sustained in living cells and tissues.

  6. Glossary of physics - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_physics

    A form of electric current in which the movement of electric charge periodically reverses direction. Contrast direct current. ammeter An instrument that is used to measure electric current. amorphous solid A type of solid which does not have a definite geometric shape. ampere (A) Often abbreviated as amp.

  7. Electric power transmission - Wikipedia

    en.wikipedia.org/wiki/Electric_power_transmission

    A 345 kV line carrying the same load across the same distance has losses of 4.2%. [25] For a given amount of power, a higher voltage reduces the current and thus the resistive losses . For example, raising the voltage by a factor of 10 reduces the current by a corresponding factor of 10 and therefore the I 2 R {\displaystyle I^{2}R} losses by a ...

  8. Reflection coefficient - Wikipedia

    en.wikipedia.org/wiki/Reflection_coefficient

    In physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors .

  9. Load line (electronics) - Wikipedia

    en.wikipedia.org/wiki/Load_line_(electronics)

    Once a DC operating point is defined by the DC load line, an AC load line can be drawn through the Q point. The AC load line is a straight line with a slope equal to the AC impedance facing the nonlinear device, which is in general different from the DC resistance. The ratio of AC voltage to current in the device is defined by this line.
