Electric power can be transmitted or distributed either by overhead transmission systems or by underground cables. Cables are mainly designed for a specific requirement. Power cables are mainly used for power transmission and distribution purposes. It is an assembly of one or more individually insulated electrical conductors, usually held together with an overall sheath. The assembly is used for transmission and distribution of electrical power.Electrical power cables may be installed as permane

What are Fiber Optics Cables Used For?Fiber optic cables (also known as optical fiber cable) are network cables that contain many strands of fine glass fibers known as optical fibers, which are kept well-insulated within the body of the cable. These cables are created for the use of long-distance, high-performance data networking, and telecommunications. Signals are transmitted through these cables by firing pulses of light through these optical fibers.In comparison to a copper-wired cable, fibe

An electrical symbol is a small image used to represent an electrical or electronic device or function. They are also known as circuit symbols or schematic symbols as they are used in electrical schematics and diagrams.Some basic electrical symbols include: Wires Diode Batteries Transformers Capacitors Resistors Inductors Fuses Switches Bipolar Junction Transistors Electromagnetic RelaysThere are many electrical and circuit symbols used internationally around the world. While they are mostly st

Transformers are one of the most common types of electrical devices, and they may be found in a variety of applications within the area of electrical engineering, including power systems. Therefore, in the position of an electrical engineer, it is usually neededto compute various characteristics of a transformer in order to establish the circumstances under which it operates. In order to do this,will need to use conventional equations, which can be seen mentioned in the sections that will follow

Another important property in AC electronic circuits, besides resistance and inductance, is capacitance. Capacitance is measured in units. The unit of capacitance is the farad. While inductance is represented in a circuit by a coil, capacitance is represented by a capacitor. In its most basic form, the capacitor is constructed of two parallel plates separated by a nonconductor, called a dielectric. In an electrical circuit, a capacitor serves as a reservoir or storehouse for electricity.Capacita

Lenz's Law, named after the Russian physicist Heinrich Lenz (1804-1865), is a fundamental principle in electromagnetism. It states that the direction of the induced electromotive force (emf) in a closed conducting loop always opposes the change in magnetic flux that caused it. This means that the induced current creates a magnetic field that opposes the initial change in magnetic flux, following the principles of conservation of energy.Understanding Lenz's Law allows us to appreciate the science

Here's a good wayto define electromagnetism -Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.The electromagnetic force is carried by electromagnetic fields composed of electric fields and magnetic fields, and it is responsible for electromagnetic radiation such as light.Who Discovered Electromagnetism?In 1820, the Danish physicist, Hans Christian Oersted, discovered that th

What is a Multimeter?A multimeter (MM) is essential for those working with electronics or electrical systems. It is a versatile instrument that combines several measurement functions into one unit, making it indispensable for electricians, technicians, and even DIY enthusiasts. This article will explore a multimeter's features, types of multimeters, and useswhile answering some common questions about this indispensable tool.Multimeters come in two primary forms: digital (DMMs) and analog multime

What is Inductance?Inductance occurs when a change in current flow is exploited for the purpose of preventing signals with a higher frequency component from passing while allowing signals of lower frequency components to pass. This is why inductors are sometimes referred to as "chokes," since they effectively choke off higher frequencies. A common application of a choke is in a radio amplifier biasing circuit where the collector of a transistor needs to be supplied with a DC voltage without allo

With the development of Photoelectric effect, Crompton’s effect and Bohr’s model of atom, the idea of light or in fact radiations in general, being composed of particles or discrete Quanta was gaining wide popularity.However, the very established Huygen’s Principle and the results of Young’s double slit experiments made it very clear that light was wave and not a flow particles.The striking interference pattern observed by passing light through double slits was definitely a result of the wave na
