Understanding the Basics of Inductors in Electronics   An inductor is an essential component in electronic circuits that store energy in a magnetic field. It is also known as a reactor or a coil. Inductors are widely used in electronic circuits for filtering out unwanted signals, storing energy, and regulating voltage output. The working principle of an inductor is based on electromagnetic induction. When current flows through an inductor, it creates a magnetic field that is proportional to the amount of current flowing through it. This magnetic field then stores energy that can be used to power other electrical devices. When the current is interrupted, the magnetic field collapses, and the stored energy is released. This process can be used to produce a voltage in a circuit or to create motion in an electromagnet. The value of an inductor is measured in henries (H). Inductance is a measure of how much energy can be stored in the magnetic field. Inductance depends on the number of ...

 Understanding the Working Principles of MOSFETs: A Comprehensive Guide MOSFETs, or metal-oxide-semiconductor field-effect transistors, are a type of transistor commonly used in electronic circuits due to their high input impedance and low power consumption. In this blog post, we will discuss the working principles, types, and applications of MOSFETs. Working Principles of MOSFETs MOSFETs are composed of a metal gate, an oxide layer, and a semiconductor channel. The gate is separated from the channel by a thin oxide layer, which acts as an insulator. The channel is doped with impurities to create an n-type or p-type semiconductor material. When a voltage is applied to the gate terminal, it creates an electric field that changes the conductivity of the channel. In an n-channel MOSFET, a positive voltage on the gate terminal attracts free electrons from the n-type channel to the oxide layer, creating a depletion region in the channel. As the gate voltage increases, the depletion regi...

A capacitor is a passive electrical component that can store energy in an electric field between two conductors separated by an insulating material, known as a dielectric. The two conductors are usually called plates, and the dielectric material can be air, paper, ceramic, or plastic. When a voltage is applied across the plates of a capacitor, an electric field is created between them. This field stores energy in the form of an electrostatic charge. The amount of charge that a capacitor can store depends on its capacitance, which is measured in farads (F). How does a...
