Diffusion capacitance definitionDiffused capacitance is a kind of differential capacitance effect of p-n junction when it is positively biased. It is caused by the diffusion process of different types of materials in semiconductor devices such as PN junction or MOSFET, that is, a few carriers in the doped region diffuse to the undoped region to form a space charge region, and finally appear as a capacitance effect.Basic principleWhen the PN junction is forward-biased, carriers (electrons and hol

What are Capacitive Loads?Capacitive loads definiteCapacitive loads are a special type of load in a circuit, used for absorbing and storing electrical energy. Compared with resistive loads, when receiving current, it will cause the voltage to lag and has a greater response to frequency. Capacitive loads have important applications in electronic circuits, power supply systems, as well as in the fields of energy transfer and storage.The following will introduce the definition of capacitive loads a

What is Diversity Factor?Diversity Factor DefinitionDiversity factor is defined as the ratio of the sum of maximum demands of individual loads to the simultaneous maximum demand of the system.Importance of Diversity FactorA high diversity factor means that a smaller electrical source can serve more loads, making it commercially viable.Peak Load TimingDifferent types of loads (domestic, commercial, industrial, etc.) have peak demands at different times, which helps in managing the overall load on

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

The unit of electrical resistance, the Ohm, is a cornerstone of the electrical world. Its importance in governing the behaviour of electric currents, designing efficient circuits, and ensuring the safe operation of devices cannot be overstated. By understanding the intricacies of resistance and Ohm's law, it is possible to harness the power of electricity to create innovative and practical solutions that benefit our daily lives.The world of electricity is complex and fascinating, with numerous c

o accurately calculate the voltage drop for a given cable size, length, and current, you need to accurately know the resistance of the type of cable you’re using. Voltage drop formulas can assist you to manually calculate voltage drop in cables that are under full load in branch circuits. It does not matter if you are working with copper oraluminum conductors.DC / single phase calculationThe voltage drop V in volts (V) is equal to the wire current I in amps (A) times 2 times one way wire size le
