  2. Inductor - Wikipedia

    en.wikipedia.org/wiki/Inductor

    An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when an electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.

  3. RL circuit - Wikipedia

    en.wikipedia.org/wiki/RL_circuit

    A resistor–inductor circuit (RL circuit), or RL filter or RL network, is an electric circuit composed of resistors and inductors driven by a voltage or current source. [1] A first-order RL circuit is composed of one resistor and one inductor, either in series driven by a voltage source or in parallel driven by a current source.

  4. Induction heater - Wikipedia

    en.wikipedia.org/wiki/Induction_heater

    Also known as the inductor, the coil is used to transfer the energy from the power unit and work head to the work piece. Inductors range in complexity from a simple wound solenoid consisting of a number of turns of copper tube wound around a mandrel, to a precision item machined from solid copper, brazed and soldered together. As the inductor ...

  5. Electromagnetic induction - Wikipedia

    en.wikipedia.org/wiki/Electromagnetic_induction

    Electromagnetic induction has found many applications, including electrical components such as inductors and transformers, and devices such as electric motors and generators. History Faraday's experiment showing induction between coils of wire: The liquid battery (right) provides a current that flows through the small coil (A) , creating a ...

  6. Choke (electronics) - Wikipedia

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

    In electronics, a choke is an inductor used to block higher-frequency alternating currents (AC) while passing direct current (DC) and lower-frequency ACs in a circuit. A choke usually consists of a coil of insulated wire often wound on a magnetic core , although some consist of a doughnut-shaped ferrite bead strung on a wire.

  7. Inductive charging - Wikipedia

    en.wikipedia.org/wiki/Inductive_charging

    An increase in high-power inductive charging devices has led to researchers looking into the safety factor of the electromagnetic fields (EMF) put off by larger inductor coils. With the recent interest in the expansion of high power inductive charging with electric cars, an increase in health and safety concerns has arisen.

  8. Induction generator - Wikipedia

    en.wikipedia.org/wiki/Induction_generator

    Because the current in an inductor is integral of the voltage with respect to time, for a sinusoidal voltage waveform the current lags the voltage by 90°, and the induction motor always consumes reactive power, regardless of whether it is consuming electrical power and delivering mechanical power as a motor or consuming mechanical power and ...

  9. RLC circuit - Wikipedia

    en.wikipedia.org/wiki/RLC_circuit

    Series RL, parallel C circuit with resistance in series with the inductor is the standard model for a self-resonant inductor. A series resistor with the inductor in a parallel LC circuit as shown in Figure 4 is a topology commonly encountered where there is a need to take into account the resistance of the coil winding and its self-capacitance.
