2. Motor capacitor - Wikipedia

   en.wikipedia.org/wiki/Motor_capacitor

   A typical motor start capacitor. A motor capacitor [1] [2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run ...

3. Capacitor - Wikipedia

   en.wikipedia.org/wiki/Capacitor

   For air dielectric capacitors the breakdown field strength is of the order 2–5 MV/m (or kV/mm); for mica the breakdown is 100–300 MV/m; for oil, 15–25 MV/m; it can be much less when other materials are used for the dielectric. [37] The dielectric is used in very thin layers and so absolute breakdown voltage of capacitors is limited.

4. Film capacitor - Wikipedia

   en.wikipedia.org/wiki/Film_capacitor

   AC capacitors serve as damping or snubbing capacitors when connected in series with a resistor, and are also specified for the damping of undesirable voltage spikes caused by the so-called charge carrier storage effect during switching of power semiconductors. In addition, AC capacitors are used in low-detuned or close-tuned filter circuits for ...

5. Capacitor types - Wikipedia

   en.wikipedia.org/wiki/Capacitor_types

   Capacitors for AC applications are primarily film capacitors, metallized paper capacitors, ceramic capacitors and bipolar electrolytic capacitors. The rated AC load for an AC capacitor is the maximum sinusoidal effective AC current (rms) which may be applied continuously to a capacitor within the specified temperature range.

6. Capacitive power supply - Wikipedia

   By changing the value of the example in the diagram by a capacitor with a value of 330 nF, a current of approximately 20 mA can be provided, as the reactance of the 330 nF capacitor at 50 Hz calculates to = and applying Ohm's law, that limits the current to . This way up to 48 white LEDs in series can be powered (for example, 3.1 V/20 mA/20000 ...

7. Electrolytic capacitor - Wikipedia

   en.wikipedia.org/wiki/Electrolytic_capacitor

   A capacitor can also act as an AC resistor. aluminium electrolytic capacitors in particular are often used as decoupling capacitors to filter or bypass undesired AC frequencies to ground or for capacitive coupling of audio AC signals. Then the dielectric is used only for blocking DC.
