  2. Equivalent series resistance - Wikipedia

    en.wikipedia.org/wiki/Equivalent_series_resistance

    This metallic resistance is small for small inductance values (typically below 1 Ω). The DC wire resistance is an important parameter in transformer and general inductor design because it contributes to the impedance of the component, and current flowing through that resistance is dissipated as waste heat, and energy is lost from the circuit ...

  3. Norton's theorem - Wikipedia

    en.wikipedia.org/wiki/Norton's_theorem

    The Norton resistance R no is found by calculating the output voltage V o produced at A and B with no resistance or load connected to, then R no = V o / I no; equivalently, this is the resistance between the terminals with all (independent) voltage sources short-circuited and independent current sources open-circuited (i.e., each independent ...

  4. Thévenin's theorem - Wikipedia

    en.wikipedia.org/wiki/Thévenin's_theorem

    The Thévenin-equivalent resistance R Th is the resistance measured across points A and B "looking back" into the circuit. The resistance is measured after replacing all voltage- and current-sources with their internal resistances. That means an ideal voltage source is replaced with a short circuit, and an ideal current source is replaced with ...

    To calculate the E96 series: is 96, then is incremented from 0 to 95 through the formula. All official values of E96 series match their calculated values. To calculate the E192 series: is 192, then is incremented from 0 to 191 through the formula, with one exception for = where 9.20 is the official value instead of the calculated 9.19 value.

  7. Equivalent impedance transforms - Wikipedia

    en.wikipedia.org/wiki/Equivalent_impedance...

    Equivalent unbalanced and balanced networks. The impedance of the series elements in the balanced version is half the corresponding impedance of the unbalanced version. Fig. 3. To be balanced, a network must have the same impedance in each "leg" of the circuit. A 3-terminal network can also be used as a 2-port.

  9. 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.
