  2. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    Capacitor-run induction motors have a permanently connected phase-shifting capacitor in series with a second winding. The motor is much like a two-phase induction motor. Motor-starting capacitors are typically non-polarized electrolytic types, while running capacitors are conventional paper or plastic film dielectric types.

    There are also capacitor-run induction motors which have a permanently connected phase-shifting capacitor in series with a second winding. The motor is much like a two-phase induction motor. Motor-starting capacitors are typically non-polarized electrolytic types, while running capacitors are conventional paper or plastic film dielectric types.

  4. Pre-charge - Wikipedia

    en.wikipedia.org/wiki/Pre-charge

    The simplest inrush-current limiting system, used in many consumer electronics devices, is a NTC resistor. When cold, its high resistance allows a small current to pre-charge the reservoir capacitor. After it warms up, its low resistance more efficiently passes the working current. Many active power factor correction systems also include soft ...

  5. Parasitic capacitance - Wikipedia

    en.wikipedia.org/wiki/Parasitic_capacitance

    They act like the plates of a capacitor, and store charge. Any change in the voltage across the coil requires extra current to charge and discharge their small capacitances. When the voltage changes only slowly, as in low-frequency circuits, the extra current is usually negligible, but when the voltage changes quickly the extra current is ...

  6. Lithium-ion capacitor - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_capacitor

    The electrolyte used in a LIC is a lithium-ion salt solution that can be combined with other organic components and is generally identical to that used in lithium-ion batteries. In general, organic electrolytes are used which have a lower electrical conductivity (10 to 60 mS/cm) than aqueous electrolytes (100 to 1000 mS/cm) but are much more ...

    The researchers combined an electric probe and an electrolyte to create a miniature battery in an attempt to understand why lithium burrowed into certain areas and caused a short circuit. When ...

  8. Supercapacitor - Wikipedia

    en.wikipedia.org/wiki/Supercapacitor

    The electrochemical charge storage mechanisms in solid media can be roughly (there is an overlap in some systems) classified into 3 types: Electrostatic double-layer capacitors (EDLCs) use carbon electrodes or derivatives with much higher electrostatic double-layer capacitance than electrochemical pseudocapacitance, achieving separation of charge in a Helmholtz double layer at the interface ...
