Inductors are passive electronic components that store electrical energy in a magnetic field when current flows through them. There are various types of inductors designed for specific applications. Here are some common types of inductors. Air Core Inductor Construction An air core inductor is an inductor formed by winding several turns of enameled wire around a […]
Self inductance and mutual inductance are concepts related to electromagnetic induction, a phenomenon discovered by Michael Faraday. These concepts are fundamental to understanding the behavior of inductors in electrical circuits. Self Inductance Self-inductance can be defined as: The phenomenon in which a change in electric current in a circuit produces an induced electro-motive-force in the
An inductor is a passive electronic component which is capable of storing electrical energy in the form of magnetic energy. Basically, it uses a conductor that is wound into a coil, and when electricity flows into the coil from the left to the right, this will generate a magnetic field in the clockwise direction. The
Magnetic materials are substances that exhibit magnetic properties, meaning they can be attracted to or repelled by a magnet. These materials are characterized by the presence of microscopic magnetic domains, where atomic magnetic moments align in a specific direction. Common examples include iron, cobalt, and nickel. Introduction of Magnetic Materials- Ferromagnetic & Ferrimagnetic Magnetism, the
The base unit of capacitance is the farad (F). This value is much too large for ordinary circuits, so household capacitors are labeled with nF, µF, or mF. In the following article we will deep dive to understand how to read a capacitor. Polarised Capacitor Electrolytic Capacitors Electrolytic capacitors are polarised and they must be connected the
The capacitor in which the capacitance value is not fixed and can be changed mechanically or electronically is called variable capacitor. The capacity of the device for storing electric charge is known as capacitance. It is given by, Where, C: Capacitance of capacitor in farad. A: Area of any one plate in m2. D: Distance between
A capacitor is a passive two-terminal electrical component used to store energy in an electric field. An electrolytic capacitor is a capacitor that uses an oxide film made of aluminum, tantalum or other oxidizable metal as a dielectric. Almost all the electrolytic capacitors are polarized, which means the voltage of the anode must always be higher than the cathode. Capacitor Simple capacitors consist of two
A capacitor (originally known as condenser) is a passive two-terminal electrical component used to store energy in an electric field. OR capacitor or condenser, device for the storage of electric charge. Simple capacitors consist of two plates made of an electrically conducting material (e.g., a metal) and separated by a non-conducting material or dielectric (e.g., glass, paraffin, mica, oil, paper, tantalum, or air). If an electrical potential (voltage) is
A potentiometer is an electrical component that provides variable resistance, and is often user-controlled. The linear variety of this component allows for gradual changes in resistance at a linear proportionality of mechanical input to electrical output. Two types of potentiometers with different tracks are available. These are Linear (Lin) or Logarithmic (Log) tracks. Linear and
The Temperature Dependent Resistor (TDR) is nothing but a thermistor. Thermistor word derived from Thermal resistor. It became available in early 1960’s. This describes the action of the thermistor particularly well. Today, thermistors are used in a wide variety of devices from temperature sensors through to providing temperature compensation in electronic circuits. As such thermistors
