An inductor, also called a coil, choke, or reactor, is a passive two-terminal electrical component that stores energy in a magnetic field when electric current flows through it. [1] An inductor typically consists of an insulated wire wound into a coil.
8 gru 2022 · Inductors are one of the most fundamental devices in circuits, a passive 2-terminal device that finishes the trifecta - resistor, capacitor, and inductor. They’re easy to deal with in ideal DC circuits but get more complicated as their impedance changes with frequency.
14 lut 2018 · Faraday invented the inductor while discovering the phenomenon of electromagnetic-induction nearly two hundred years ago, which subsequently proved crucial for practical large scale use of electricity for power and telegraph communication.
A more complete list of events that marked the induction motor history follows. Better and better analytical models for steady state and design purposes. The orthogonal (circuit) and space phasor models for transients. Better and better magnetic and insulation materials and cooling systems.
In honor of Henry, the SI unit of inductance bears his name. One henry equals the inductance of a circuit with an induced voltage of one volt and an inducing current that changes one ampere per second. Henry was born to Scottish immigrants living in Albany, New York, on December 17, 1797.
19 paź 2023 · Inductors are coils of copper wire used to create a magnetic field. This magnetic field can then be used to generate an electric field. The voltage induced in an inductor is proportional to the rate of change of current.
21 gru 2023 · Inductors have a long history of use in electronic systems. In fact, one of the most common uses in the home is as an integral part of a typical loudspeaker system. They are used in modern switch-mode DC power supplies in products such as personal computers and televisions.
