Electrostatics

Dielectrics have zero or deficient electrical charge. They are also called non-conductors because they do not allow the current to flow easily; hence they cannot be charged. This feature makes them useful in different industries.  Dielectrics  are insulating materials because they do not conduct current. They are ubiquitous in capacitors, transformers, and loudspeakers. Importance of […]

A varactor diode is a reverse-biassed p-n junction diode with electrically variable capacitance. Varactor, tuning diodes, voltage variable capacitor diodes, parametric diodes, and variable capacitor diodes are all terms used to describe these diodes. The varactor diode has a symbol that is comparable to the PN-junction diode. Anode and cathode are the two terminals of

We all know V-I characteristics, as they represent the voltage and current characteristics. The V-I characteristics are used to know about the resistance and break down in electronic components and provide the operating region of a component. There are two types of V-I characteristics. V-l characteristics of Ohmic conductors  V-l characteristics of non-ohmic conductors. So,

The Capacitor is one of the three major components in an electrical circuit. It is most commonly used as a reservoir for stored energy. In addition to this, it also serves as a filter or power supply that helps regulate voltage in electrical circuits. Moreover, it can also break down alternating current into direct current

The floors of centre column suspended constructions are suspended or supported by high-strength cable. In some cases, beams are cantilevered out from the building’s central concrete column. The roof system and the walls are supported by cables that run from the top of the main column. From the top of the tower, cables reach down

Surface tension is a feature of a liquid surface that manifests itself as a stretched elastic membrane. This effect can be seen in the nearly spherical shape of small liquid drops and soap bubbles. Because of this property, several insects may stand on the water’s surface. The surface tension of water may support a razor

As with a rechargeable battery, a Spherical Capacitor can accumulate energy as a charge, which produces a potential difference or (Static Voltage) in-between its plates. Tiny beads used in resonance circuits and large capacitors used to correct power factors can store charge, but they have the same function. There are capacitors composed of two or

The intense sticky and viscous lava that forms a shield volcano. In comparison to other types of volcanoes, it has shallow inclining sides and is wide. The volcano creates numerous layers of lava on the surface after multiple eruptions until the magma in the earth’s underneath chamber is exhausted. When magma erupts and descends to

A capacitor is a fundamental electronic component that has the ability to store electric charges. A capacitor is made of two metallic plates (also known as conductors) separated by an insulator (dielectric).  The capacitance of a capacitor C is given by Q is the charge on the two metallic plates.  V is the potential difference

Materials with conductivity intermediate between conductors (usually metals) and non-conductors or insulators are referred to as semiconductor materials (such as ceramics). Semiconductors, such as gallium arsenide, or pure elements such as germanium or silicon can be used as semiconductors. For example, gallium arsenide, germanium, and silicon are all types of semiconductor materials. Gallium  arsenide is
