How to Measure Resistance

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 […]

Coulombs Law

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 […]

Electric charge

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 […]

Ohmmeter Working and Types

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 […]

What is SF6 Circuit Breaker?

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 (ACB)

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, […]

Air Blast Circuit Breaker

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 […]

Oil Circuit Breaker

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 […]

Vacuum Circuit Breaker

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 […]
