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. An inductor typically consists of an insulated wire wound into a coil.
Inductors, much like conductors and resistors, are simple components that are used in electronic devices to carry out specific functions. Normally, inductors are coil-like structures that are found in electronic circuits. The coil is an insulated wire that is looped around the central core.
Apr 22, 2024 · Inductors are used to store energy in the form of magnetic field when an electric current is passed through it. This article will cover inductors, its types, its functions and the difference between inductors and capacitors.
Oct 29, 2021 · An inductor (also known as an electrical inductor) is defined as a two-terminal passive electrical element that stores energy in the form of a magnetic field when electric current flows through it. It is also called a coil, chokes, or reactor.
Dec 8, 2022 · The ability to store energy in the electric fields is measured in the units of henry, or henries, named after the guy who discovered the principle of inductance. For most real-life scenarios, particularly for electronics applications, most inductors are a small fraction of a henry.
Inductors are formed with wire tightly wrapped around a solid central core which can be either a straight cylindrical rod or a continuous loop or ring to concentrate their magnetic flux. The schematic symbol for a inductor is that of a coil of wire so therefore, a coil of wire can also be called an Inductor.
What about the inductor? When the switch is closed, the current that points right-to-left for the inductor increases in the direction of the loop. As a result of Faraday's law, the inductor becomes a "smart battery" that acts to reduce the current, which means there is a voltage drop: \[\mathcal E_{inductor} = -L\dfrac{dI}{dt}\]
Dec 8, 2000 · To understand how an inductor can work in a circuit, this figure is helpful: What you see here is a battery, a light bulb, a coil of wire around a piece of iron (yellow) and a switch. The coil of wire is an inductor. If you have read How Electromagnets Work, you might recognize that the inductor is an electromagnet.
Nov 25, 2018 · In this tutorial let us understand the basics of an Inductor and demystify it so that we will know how and when to use one in our applications. What is an Inductor? The inductor is perhaps the simplest of all electronic components, constructed much like a resistor – a simple length of wire that is coiled up. However, here, resistance is not ...
