  2. ESR meter - Wikipedia

    en.wikipedia.org/wiki/ESR_meter

    Measuring ESR can be done by applying an alternating voltage at a frequency at which the capacitor's reactance is negligible, in a voltage divider configuration. It is easy to check ESR well enough for troubleshooting by using an improvised ESR meter comprising a simple square-wave generator and oscilloscope, or a sinewave generator of a few tens of kilohertz and an AC voltmeter, using a known ...

  3. Integrated passive devices - Wikipedia

    en.wikipedia.org/wiki/Integrated_passive_devices

    The earliest form of IPDs are resistor, capacitor, resistor-capacitor (RC) or resistor-capacitor-coil/inductor (RCL) networks. Passive transformers can also be realised as integrated passive devices like by putting two coils on top of each other separated by a thin dielectric layer.

  4. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    Snubber capacitors are usually employed with a low-value resistor in series, to dissipate energy and minimize RFI. Such resistor-capacitor combinations are available in a single package. Capacitors are also used in parallel to interrupt units of a high-voltage circuit breaker to distribute the voltage between these units equally. In this case ...

  5. RKM code - Wikipedia

    en.wikipedia.org/wiki/RKM_code

    For brevity, the notation omits to always specify the unit (ohm or farad) explicitly and instead relies on implicit knowledge raised from the usage of specific letters either only for resistors or for capacitors, [nb 1] the case used (uppercase letters are typically used for resistors, lowercase letters for capacitors), [nb 2] a part's appearance, and the context.

  6. Generator (circuit theory) - Wikipedia

    en.wikipedia.org/wiki/Generator_(circuit_theory)

    A generator in electrical circuit theory is one of two ideal elements: an ideal voltage source, or an ideal current source. [1] These are two of the fundamental elements in circuit theory. Real electrical generators are most commonly modelled as a non-ideal source consisting of a combination of an ideal source and a resistor.

  7. Inrush current - Wikipedia

    en.wikipedia.org/wiki/Inrush_current

    A resistor in series with the line can be used to limit the current charging input capacitors. However, this approach is not very efficient, especially in high-power devices, since the resistor will have a voltage drop and dissipate some power. Inrush current can also be reduced by inrush current limiters.
