  2. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    In the short-time limit, if the capacitor starts with a certain voltage V, since the voltage drop on the capacitor is known at this instant, we can replace it with an ideal voltage source of voltage V.

  3. 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.

    Select capacitor C 2, replace it by a test voltage V X, and replace C 1 by an open circuit. Then the resistance seen by the test voltage is found using the circuit in the middle panel of Figure 1 and is simply V X / I X = R 1 + R 2. Form the product C 2 ( R 1 + R 2). Select capacitor C 1, replace it by a test voltage V X, and replace C 2 by an open

    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 ...

    An electrolytic capacitor is a polarized capacitor ... Niobium electrolytic chip capacitors are a new development in the market and are intended as a replacement for ...

  7. Polymer capacitor - Wikipedia

    en.wikipedia.org/wiki/Polymer_capacitor

    These capacitors were used in devices for applications that required the lowest possible ESR or highest possible ripple current. One OS-CON e-cap could replace three more bulky "wet" e-caps or two Ta-caps. [8] By 1995, the Sanyo OS-CON became the preferred decoupling capacitor for Pentium processor-based IBM personal computers.
