Breakdown voltage is a term that is commonly used in the field of electrical engineering. It refers to the voltage at which an insulator or a semiconductor material suddenly becomes conductive, allowing an electric current to pass through it. This phenomenon is known as electrical breakdown and is an important consideration in the design and operation of electrical systems.
Definitions
Breakdown voltage can be defined as the minimum voltage required to cause a material to become electrically conductive. It is the point at which the material’s resistance drops from being infinite to being very low. The breakdown voltage is usually measured in volts (V) and can be determined using various methods, including the Paschen curve, the Townsend discharge, and the avalanche breakdown.
Origin
The concept of breakdown voltage has been around since the early days of electricity. It was first observed in the 19th century by scientists such as Michael Faraday and James Clerk Maxwell. They noticed that when an electric field was applied to certain materials, they would suddenly become conductive, allowing an electric current to pass through them. This was the first indication of the breakdown voltage phenomenon.
Meaning in different dictionaries
The breakdown voltage has a specific meaning in the field of electrical engineering, but it can also be found in various dictionaries. In the Merriam-Webster dictionary, it is defined as “the voltage at which a dielectric breaks down and becomes a conductor.” The Oxford English Dictionary defines it as “the voltage at which an insulator becomes conductive.”
Associations
The breakdown voltage is an important consideration in the design and operation of electrical systems. It is used to determine the maximum voltage that can be safely applied to a particular material or component. It is also used to design protective devices such as fuses and circuit breakers, which are designed to prevent damage to electrical equipment in the event of a voltage spike or surge.
Synonyms
Some synonyms for breakdown voltage include breakdown potential, dielectric strength, and insulation resistance.
Antonyms
There are no direct antonyms for breakdown voltage, but it is often contrasted with the concept of insulation resistance, which is the measure of a material’s ability to resist the flow of electric current.
The same root words
The root words of breakdown voltage are “breakdown” and “voltage.” Breakdown refers to the sudden change in a material’s conductivity, while voltage refers to the electrical potential difference between two points.
Example Sentences
- The breakdown voltage of this insulator is 10 kV.
- The circuit breaker is designed to trip when the voltage exceeds the breakdown voltage of the component.
- The insulation resistance of this material is high, which means it has a high breakdown voltage.
- The Paschen curve is a graph that shows the relationship between breakdown voltage and pressure in a gas.
- The avalanche breakdown occurs when a high-energy electron collides with an atom, causing it to release additional electrons and creating a chain reaction that leads to electrical breakdown.
