What is a Vacuum Circuit Breaker? Vacuum circuit breaker definition Vacuum circuit breaker is a kind of high voltage switchgear which uses the arc extinguishing characteristic in vacuum environment to disconnect and connect the high voltage circuit. Compared with traditional circuit breakers such as

What is SF6 Circuit Breaker? SF6 Circuit breaker definition SF6 circuit breaker is a high-voltage circuit breaker using SF6 gas as insulation and arc extinguishing medium. SF6 gas has excellent insulation performance and arc extinguishing ability, which makes SF6 circuit breaker become one of the wi

What is an Air Switch? Air circuit breaker definition Air circuit breaker is a kind of high voltage circuit breaker which uses air as arc extinguishing medium. Compared with other types of high-voltage circuit breakers such as SF6 circuit breakers and vacuum circuit breakers, air circuit breakers ar

What is a Mixed Media Circuit Breaker? Mixed media circuit breaker definition Mixed-medium circuit breaker is a high-voltage circuit breaker that uses a variety of media (usually a combination of gas and solid materials) as insulation and arc extinguishing media. This type of circuit breaker is desi

What is Schottky Effect? Schottky Effect Definition The Schottky effect is defined as a reduction in the energy needed to remove electrons from a solid surface in a vacuum when an electric field is applied. This boosts electron discharge from heated materials and impacts the thermionic current, surf

What is an Optoisolator? Optoisolator Definition An optoisolator (also known as an optocoupler or optical isolator) is defined as an electronic component that transfers electrical signals between two isolated circuits using light. Working Principle The input circuit consists of a variable voltage so

What are Valence Electrons and Electrical Conductivity ? Valence Electrons Definition An atom is made up of a nucleus containing protons and neutrons, with electrons in shells around it. The nucleus is positively charged, and the electrons are negatively charged. Atoms are electrically neutral becau

What are Photo Electrons? Photoelectron Definition A photoelectron is defined as an electron emitted from a material when it absorbs light energy. This emission process is called the photoelectric effect and it provides key evidence for the quantum nature of light and matter. This article will expla

What is Slew Rate? Slew Rate Definition In electronics, the slew rate is defined as the maximum rate of output voltage change per unit time. It is denoted by the letter S. The slew rate helps us to identify the amplitude and maximum input frequency suitable to an operational amplifier (OP amp) such

Mobility of Charge Carrier Definition Mobility of charge carriers is defined as the ratio of drift velocity to the applied electric field in a conductor. Drift velocity depends on two factors: the intensity of the electric field and the conductor’s mobility. For the same electric field, different me

What is Electrical Conductance? The definition of conductivity This property determines how easily the current flows through the conductor. As we all know, resistance is a property of a conductor that resists current flowing through it. This means that the conductivity is the reciprocal number of re

What is a MOS Capacitor? MOS Capacitor Defined MOS stands for Metal Oxide Semiconductor. An MOS capacitor comprises a semiconductor body or substrate, an insulator, and a metal gate. Typically, the gate is made from heavily doped n+ poly-silicon that functions like metal. Silicon dioxide (SiO2) serv
