What is Valence Band? Valence band is defined as the energy band that contains the valence electrons present in the outermost shell of an atomic structure. It is commonly abbreviated as VB. Electrons are present in the valence band so it is either partially or completely filled. Valence band is present below the forbidden energy …

What is Slip Ring Induction Motor? These induction motors are those that use a rotor with a slip ring. Three of the ends are exposed and linked to other slip rings, and their construction is based on three-phase windings wound in a star configuration. It features a cylindrical core made of laminated steel, and its …

What is a Single Phase? Voltage fluctuations in a single-phase supply happen everywhere at once. Due to its prevalence in household settings, single-phase current is sometimes referred to as “residential voltage.” In a single-phase setup, power is transmitted along both the phase and neutral wires. The operation of a single-phase connection is conventional and easy …
What is Power? Power refers to the ability or speed at which a machine can do its required work. Power can also be alternatively called as horsepower. A vehicle’s power is directly proportionate to its speed and acceleration. In other words, when a vehicle is said to have high power, it also means that it …
What is FDM? FDM is the abbreviation of frequency division multiplexing. It is a technique for sending multiple signals of different frequencies for transmission from a single medium or channel. FDM separates various bands to transmit multiple signals through a single line or channel successfully. FDM, after separating these bands, assigns the bands to the …
What is Current Transformer? Current transformers, also alternatively known as “CTs,” are those transformers responsible for altering voltage by multiplying or reducing currents. They are used to measure currents in alternative circuits. A CT is usually used as a backup or secondary current-producing mechanism that matches the primary current-producing machine by measuring it. In other …

What is Autotransformer? An autotransformer is a transformer in which the same winding serves as both the main and secondary windings. The autotransformer’s windings are electrically and magnetically linked to one another. This means that the same winding performs the primary and secondary functions of an autotransformer. As a result, the autotransformer’s windings share a …

What is an Active Filter? An active filter is an analog circuit that implements an electronic filter with an active component like an amplifier. Adding amplifiers to a filter design can improve its cost, performance, and predictability. In an active filter, an amplifier prevents the load impedance of the next stage from affecting the filter …
What is Wattmeter? The wattmeter is a device that measures the active electric power (or the average rate of flow of electrical energy) of any given circuit in watts. Electromagnetic wattmeters measure utility and audio frequency power; radio frequency measurements require other types. An electrodynamic device is the traditional analog wattmeter. The gadget comprises two …
What is Transducer? A transducer is a device or algorithm that converts energy from one form to another. In electrical engineering, for example, a transducer can convert electrical energy into mechanical energy (such as in a motor) or vice versa (such as in a generator). In computer science, a transducer is an algorithm that processes …
