  2. Randles circuit - Wikipedia

    en.wikipedia.org/wiki/Randles_circuit

    Randles circuit schematic. In electrochemistry, a Randles circuit is an equivalent electrical circuit that consists of an active electrolyte resistance R S in series with the parallel combination of the double-layer capacitance C dl and an impedance (Z w) of a faradaic reaction.

  3. Warburg element - Wikipedia

    en.wikipedia.org/wiki/Warburg_element

    The Warburg diffusion element is an equivalent electrical circuit component that models the diffusion process in dielectric spectroscopy. That element is named after German physicist Emil Warburg . A Warburg impedance element can be difficult to recognize because it is nearly always associated with a charge-transfer resistance (see charge ...

  4. Constant phase element - Wikipedia

    en.wikipedia.org/wiki/Constant_phase_element

    In electronics, a constant phase element is an equivalent electrical circuit component that models the behaviour of a double layer, that is, an imperfect capacitor (see double-layer capacitance). Constant phase elements are also used in equivalent circuit modeling and data fitting of electrochemical impedance spectroscopy data.

  5. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    For a simplified model of a capacitor as an ideal capacitor in series with an equivalent series resistance, the capacitor's quality factor (or Q) is the ratio of the magnitude of its capacitive reactance to its resistance at a given frequency:

  6. Capacitor types - Wikipedia

    en.wikipedia.org/wiki/Capacitor_types

    All properties can be defined and specified by a series equivalent circuit composed out of an idealized capacitance and additional electrical components which model all losses and inductive parameters of a capacitor. In this series-equivalent circuit the electrical characteristics are defined by: C, the capacitance of the capacitor

  7. Tantalum capacitor - Wikipedia

    en.wikipedia.org/wiki/Tantalum_capacitor

    Series-equivalent circuit model of a tantalum capacitor Tantalum electrolytic capacitors as discrete components are not ideal capacitors, as they have losses and parasitic inductive parts. All properties can be defined and specified by a series equivalent circuit composed of an idealized capacitance and additional electrical components which ...

  8. Electrolytic capacitor - Wikipedia

    en.wikipedia.org/wiki/Electrolytic_capacitor

    Series-equivalent circuit model of an electrolytic capacitor The electrical characteristics of capacitors are harmonized by the international generic specification IEC 60384-1. In this standard, the electrical characteristics of capacitors are described by an idealized series-equivalent circuit with electrical components which model all ohmic ...

  9. Equivalent circuit - Wikipedia

    en.wikipedia.org/wiki/Equivalent_circuit

    Often, an equivalent circuit is sought that simplifies calculation, and more broadly, that is a simplest form of a more complex circuit in order to aid analysis. [1] In its most common form, an equivalent circuit is made up of linear, passive elements. However, more complex equivalent circuits are used that approximate the nonlinear behavior of ...
