Definition
- Noun:
- An electrical device that introduces inductance into a circuit: An "inductor" is a passive electronic component, typically consisting of a coil of wire, that stores energy in a magnetic field when electric current flows through it. It resists changes in current.
Usage
- An "inductor" is used in electrical circuits to control current, filter signals, or store energy. It is a fundamental component alongside resistors and capacitors.
- Example:
- Example:
Advanced Usage
- "Air-core inductor": An inductor where the coil is wound around a non-magnetic form, used in high-frequency applications to minimize losses.
- An air-core inductor was chosen for the transmitter to avoid core saturation.
- "Toroidal inductor": An inductor where the coil is wound around a ring-shaped (toroidal) core, which confines the magnetic field efficiently.
- The toroidal inductor has less electromagnetic interference than a solenoid type.
Variants and Related Words
- Inductance (n): The property of an electrical conductor or circuit that causes an electromotive force to be generated by a change in the current flowing through it. It is measured in henries.
- The inductance of the coil determines its ability to store magnetic energy.
- Inductive (adj): Relating to or operating by electrical or magnetic induction.
- The sensor works on an inductive principle.
Synonyms
- Coil: A more general term for a length of wire wound into a series of loops, which can function as an inductor.
- Choke: A type of inductor specifically used to block (choke) high-frequency alternating current while allowing direct or low-frequency current to pass.
- Reactor: In electrical engineering, a term sometimes used for an inductor, especially one used in power systems.
