2. ESR meter - Wikipedia

   en.wikipedia.org/wiki/ESR_meter

   A typical ESR Meter. This one also measures capacitance. An ESR meter is a two-terminal electronic measuring instrument designed and used primarily to measure the equivalent series resistance (ESR) of real capacitors; usually without the need to disconnect the capacitor from the circuit it is connected to.

3. Equivalent series resistance - Wikipedia

   en.wikipedia.org/wiki/Equivalent_series_resistance

   Capacitors and inductors as used in electric circuits are not ideal components with only capacitance or inductance.However, they can be treated, to a very good degree of approximation, as being ideal capacitors and inductors in series with a resistance; this resistance is defined as the equivalent series resistance (ESR) [1].

4. Capacitance meter - Wikipedia

   en.wikipedia.org/wiki/Capacitance_meter

   A capacitance meter is a piece of electronic test equipment used to measure capacitance, [1] mainly of discrete capacitors. Depending on the sophistication of the meter, it may display the capacitance only, or it may also measure a number of other parameters such as leakage, equivalent series resistance (ESR), and inductance.

5. LCR meter - Wikipedia

   en.wikipedia.org/wiki/LCR_meter

   Handheld LCR meters typically have selectable test frequencies of 100 Hz, 120 Hz, 1 kHz, 10 kHz, and 100 kHz for top end meters. The display resolution and measurement range capability will typically change with the applied test frequency since the circuitry is more sensitive or less for a given component (i.e., an inductor or capacitor) as the ...

6. Multimeter - Wikipedia

   en.wikipedia.org/wiki/Multimeter

   Analog multimeter Digital multimeter A multimeter (also known as a volt-ohm-milliammeter , volt-ohmmeter or VOM ) [ 1 ] is a measuring instrument that can measure multiple electrical properties. [ 2 ] [ 3 ] A typical multimeter can measure voltage , resistance , and current , [ 4 ] in which case can be used as a voltmeter , ohmmeter , and ammeter .

7. Dissipation factor - Wikipedia

   en.wikipedia.org/wiki/Dissipation_factor

   In a capacitor made of a dielectric placed between conductors, the typical lumped element model includes a lossless ideal capacitor in series with a resistor termed the equivalent series resistance (ESR) as shown below. [1] The ESR represents losses in the capacitor. In a good capacitor the ESR is very small, and in a poor capacitor the ESR is ...

8. Electrolytic capacitor - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_capacitor

   C, the capacitance of the capacitor; R ESR, the equivalent series resistance which summarizes all ohmic losses of the capacitor, usually abbreviated as "ESR" L ESL, the equivalent series inductance which is the effective self-inductance of the capacitor, usually abbreviated as "ESL". R leak, the resistance representing the leakage current of ...

9. Aluminum electrolytic capacitor - Wikipedia

   en.wikipedia.org/.../Aluminum_electrolytic_capacitor

   This DC current is represented by the resistor R leak in parallel with the capacitor in the series-equivalent circuit of electrolytic capacitors, and flows if a voltage is applied. The leakage current includes all weak imperfections of the dielectric caused by unwanted chemical processes and mechanical damage and is the DC current that can pass ...
