Single Phase Electricity is a form of alternating current system that usually consists of a phase line (live line) and a neutral line (neutral line) with a voltage of 220V or 230V (depending on the region). Single-phase electricity is mainly used in homes, small business establishments, or occasions that do not require a large amount of electricity. Here are a few common appliances that can run on single-phase electricity:Household appliance Lighting fixtures: such as LED lamps, fluorescent lamp

What is Solar Electricity?Solar Electricity DefinitionSolar electricity is produced by sunlight hitting photovoltaic cells, generating power.Photovoltaic EffectSolar energy electrical engineering relies on the photovoltaic effect, where sunlight creates electricity in semiconductor materials.Structure of Solar CellsA solar cell consists of a thin n-type layer on top of a thicker p-type layer, with a depletion region at their junction.Charge SeparationSunlight causes electrons to move to the n-la

The Nature of Electricity?Definition of electricityThe flow of electrons through a conductor due to an electric potential difference.The fundamental properties of electricityWhen a negatively charged object is connected to a positively charged object through a conductor, excess electrons flow from the negative body to the positive body to balance the electron shortage.Atomic structureAn atom consists of a nucleus with protons and neutrons, surrounded by electrons.Free electronLoose bonds combine

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

What is Alternating Current?Alternating current is a fundamental aspect of electrical systems that have shaped our world in countless ways. Its ability to be easily generated, converted to different voltages, and transmitted over long distances has made it the preferred choice for power transmission and distribution. Additionally, the many advantages of AC, such as compatibility with various devices and safety features, have made it indispensable in our daily lives.In the world of electricity, t

Now consider an AC circuit with two voltage sources. Here, magnitude, polarity, and phase angle are used to find the equivalent voltage. Electrical Polarity in AC Voltages In the first figure, both sources have the same polarity. Hence, the equivalent voltage is the addition of both. But these are the polar form—First, we need to convert this polar form into a rectangular form. And it will be—Now, the equivalent voltage is the addition of each of the X-components and Y-components (i.e. )—Agai

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 applied to a conductor, the current starts flowing, or the free electrons start moving. While moving, the free electrons collide with the atoms and

Electricity is the most common form of energy. Electricity is used for various applications such as lighting, transportation, cooking, communication, production of various goods in factories and much more. None of us exactly know that what is electricity. The concept of electricity and theories behind it, can be developed by observing its different behaviors. For observing nature of electricity, it is necessary to study the structure of matters. Every substance in this universe is made up of ext
