The dielectric strength of nitrogen is _________.

Explanation:

Dielectric Strength of Nitrogen

Definition: Dielectric strength is defined as the maximum electric field that a material can withstand without experiencing failure of its insulating properties. In simpler terms, it is the highest voltage that can be applied across a material without causing it to conduct electricity (breakdown). For gases, such as nitrogen, this value is typically given in volts per millimeter (V/mm).

Dielectric Strength of Nitrogen: The dielectric strength of nitrogen is an important parameter in various applications, especially in electrical and electronic engineering. Nitrogen is commonly used as an insulating gas in high-voltage equipment, such as transformers and circuit breakers. It is also used in the semiconductor industry for creating inert atmospheres during manufacturing processes.

The dielectric strength of nitrogen is approximately 3 to 5 V/mm. This means that nitrogen can withstand an electric field of 3 to 5 volts per millimeter before it breaks down and becomes conductive.

Correct Option Analysis:

The correct option is:

Option 4: 3 to 5 V/mm

This option correctly states the dielectric strength of nitrogen. As mentioned, the dielectric strength of nitrogen ranges from 3 to 5 V/mm, making it a suitable insulating material for various high-voltage applications.

Additional Information

To further understand the analysis, let’s evaluate the other options:

Option 1: 1 to 2 V/mm

This option is incorrect. The dielectric strength of nitrogen is higher than this range. A value of 1 to 2 V/mm is significantly lower than the actual dielectric strength of nitrogen, which means nitrogen would not be a reliable insulating material if this were the case.

Option 2: 6 to 7 V/mm

This option is also incorrect. While nitrogen has good insulating properties, its dielectric strength does not typically reach as high as 6 to 7 V/mm. This value is higher than the actual dielectric strength of nitrogen, which could lead to overestimating its insulating capabilities.

Option 3: 7 to 8 V/mm

Similar to option 2, this range is too high. The dielectric strength of nitrogen does not reach 7 to 8 V/mm under normal conditions. Using this value could result in incorrect assumptions about the performance of nitrogen as an insulating gas.

Conclusion:

Understanding the dielectric strength of insulating materials is crucial for designing and maintaining high-voltage equipment. The dielectric strength of nitrogen, at 3 to 5 V/mm, makes it a reliable and effective insulating gas for various applications. By correctly identifying this parameter, engineers can ensure the safety and efficiency of electrical systems that utilize nitrogen as an insulator.
