Electrical4UWhat is a Fast Recovery Diode? A fast recovery diode (also known as a fast diode or fast switching diode) is defined as a semiconductor device with a short reverse recovery time. Because fast recovery diodes have a lower reverse recovery time than conventional diodes, they are better suited to high-frequency rectification applications. As fast … Read more
What is an Inductor? 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. An inductor is simply a coil of wire. It usually … Read more
What is a Shunt Resistor? A shunt resistor (or shunt) is defined as a device that creates a low resistance path to force most of the electric current through the circuit to flow through this path. In most cases, a shunt resistor is made up of a material having a low-temperature coefficient of resistance, giving … Read more
What is a Berry Type Transformer? A transformer with a core that looks like a spoke of the wheel is known as a berry type transformer (or “berry transformer” for short). According to the type of core, transformers can be classified into three types; Core type transformer Shell type transformer Berry type transformer Sometimes, a … Read more
What is Ohm’s Law? Ohm’s law states that the electrical current flowing through any conductor is directly proportional to the potential difference (voltage) between its ends, assuming the physical conditions of the conductor do not change. In other words, the ratio of potential difference between any two points of a conductor to the current flowing … Read more
What is a Transformer Connection? The primary and secondary winding of a three-phase transformer can be connected in different ways according to available terminals and the desired application. A three-phase transformer is constructed by three single-phase transformers on separate cores, or on one combined core. But in most cases, the three-phase winding is placed on … Read more
What is Stroboscopic Motion? Stroboscopic motion (also known as the Stroboscopic Effect) is defined as a visual phenomenon that occurs when continuous rotational motion is represented by a series of short samples (as opposed to a continuous view) at a sampling rate close to the period of the motion. An example of stroboscopic motion is … Read more
What is Electrical Resistance? Resistance (also known as ohmic resistance or electrical resistance) is a measure of the opposition to current flow in an electrical circuit. Resistance is measured in ohms, symbolized by the Greek letter omega (Ω). The larger resistance, the greater the barrier against the flow of current. When the potential difference is … Read more
What is Clamping Voltage? Clamping voltage is defined as the maximum voltage allowed to pass through an electrical circuit breaker or surge protector before limiting further voltage from passing through the circuit. The clamping voltage technique is used in modern electrical equipment to protect from electrical surges. The clamping voltage is a predefined voltage for … Read more
What is a Dead Short? A dead short is an electrical circuit that results in current flowing along an unintended path with no resistance or impedance. This results in an excessive current flowing through the circuit, which can damage equipment or cause electrical shocks to those nearby. A dead short is difficult to track and … Read more
