  2. Electrical reactance - Wikipedia

    en.wikipedia.org/wiki/Electrical_reactance

    In electrical circuits, reactance is the opposition presented to alternating current by inductance and capacitance. [1] Along with resistance, it is one of two elements of impedance; however, while both elements involve transfer of electrical energy, no dissipation of electrical energy as heat occurs in reactance; instead, the reactance stores energy until a quarter-cycle later when the energy ...

  3. LC circuit - Wikipedia

    en.wikipedia.org/wiki/LC_circuit

    An LC circuit, also called a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor, represented by the letter L, and a capacitor, represented by the letter C, connected together.

  4. Inductor - Wikipedia

    en.wikipedia.org/wiki/Inductor

    The winding resistance appears as a resistance in series with the inductor; it is referred to as DCR (DC resistance). This resistance dissipates some of the reactive energy. The quality factor (or Q) of an inductor is the ratio of its inductive reactance to its resistance at a given frequency, and is a measure of its efficiency. The higher the ...

  5. Capacitor - Wikipedia

    en.wikipedia.org/wiki/Capacitor

    A capacitor may also be labeled with its working voltage, temperature, and other relevant characteristics. Example: A capacitor labeled or designated as 473K 330V has a capacitance of 47 × 10 3 pF = 47 nF (±10%) with a maximum working voltage of 330 V. The working voltage of a capacitor is nominally the highest voltage that may be applied ...

  6. Reactance - Wikipedia

    en.wikipedia.org/wiki/Reactance

    Reactance may refer to: . Electrical reactance, the opposition to a change in voltage due to capacitance (capacitive reactance) or in current due to inductance (inductive reactance); the imaginary component of AC impedance

  7. Static synchronous compensator - Wikipedia

    en.wikipedia.org/wiki/Static_synchronous_compensator

    The VI characteristic can be divided into two distinct parts: a slopped region between its inductive and capacitive maximums, and its maximum operating points. While in the slopped region between its maximums, the STATCOM is said to be in voltage regulation mode, where it either supplies capacitive vars to increase the voltage or consumes ...

  8. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    A series RLC network (in order): a resistor, an inductor, and a capacitor Tuned circuit of a shortwave radio transmitter.This circuit does not have a resistor like the above, but all tuned circuits have some resistance, causing them to function as an RLC circuit.

  9. Stub (electronics) - Wikipedia

    en.wikipedia.org/wiki/Stub_(electronics)

    The stub is made capacitive or inductive according to whether the main line presents an inductive or capacitive impedance, respectively. This is not the same as the actual impedance of the load since the reactive part of the load impedance will be subject to impedance transformer action and the resistive part.
