How is the Resistance Measured? To measure an electrical resistance (Low resistance, Medium resistance, and High resistance) electronic instruments use two measurement techniques. They are constant voltage and constant current. The constant voltage method measures […]
There is various electronic test equipment for testing electronic components and find out problems in electronic circuits. But before going to know about the list of electrical test equipment. Let’s know, what is debugging? and […]
Coulomb’s law definition in physics is explained by the concept of electric charge and electric force. According to Electricity, moving electric charges experience force when kept in a magnetic field. Here the charge is in […]
What is Electric Charge in Physics? In physics, Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. An electromagnetic field is a physical […]
What is an Ohmmeter? An ohmmeter is an electrical instrument used to measure the resistance in a circuit or a component. The opposition to the flow of electric current is a measure of resistance in […]
SF6 circuit breaker uses SF6 (Sulfur Hexafluoride) gas as an air quenching medium. This gas is electro-negative and it has high dielectric strength to absorb free electrons. This is very effective for high voltage applications […]
Air break circuit breaker uses atmospheric pressure in air as an air quenching medium. This type of circuit breaker employs a high resistance interruption principle. The arc runners and chutes increase the arc length. Moreover, […]
What is Air Blast Circuit Breaker? In this Air blast circuit breaker, it uses a high-pressure air as the arc quenching medium. In this type of circuit breaker when the contacts are separated, high-pressure air […]
What is an Oil Circuit Breaker? The oil circuit breaker has an insulating oil which is used as an arc quenching medium for arc extinction. Oil has better insulating property than air. It consists of […]
The vacuum circuit breaker (also known as vacuum interrupter or VCB) uses the arc quenching process in the vacuum as a switching medium. The vacuum has the highest insulating strength. So, it has far superior […]
