Why should the conductor have a greater strength than the system working pressure?

When discussing the relationship between conductor strength and system working pressure, we need to clarify the meanings of these two concepts. Conductor strength usually refers to a material's ability to resist external forces, while system working pressure refers to the force acting on a unit area within a specific system, which depends on the system's operating conditions and environment. In analyzing this problem, we can consider several aspects:

Strength of the conductor

The Relationship Between Resistance and Thickness

One manifestation of a conductor's strength is its ability to resist the flow of current, which is mainly measured by resistance. The search results show that the thickness of the wire has an impact on its resistance, i.e., thicker wires have lower resistance. This indicates that under the same voltage, thicker wires can carry a larger current, thus exhibiting stronger tensile strength.

The Relationship between Electric Field and Conductivity Strength

The strength of a conductor is also related to the intensity of the electric field. Search results mention that when the electric field between conductors is strong enough, it can ionize the air, forming a conductive path. This means that under the action of a high electric field, the conductor can effectively conduct current, which is also a manifestation of the strength of the conductor.

System Working Pressure

The Relationship Between Pressure and Current

The operating pressure of a system may affect the current flowing through a conductor. If the system exerts greater pressure on the conductor, it may alter the physical state of the conductor (such as deformation), which in turn affects its electrical conductivity performance. However, the search results do not provide directly relevant information to support this point.

The Relationship Between Voltage and Current

The working pressure of the system can also indirectly affect the current by changing the voltage applied to the conductor. According to Ohm's Law, there is a direct relationship between voltage and current (ignoring changes in temperature), i.e., the higher the voltage, the greater the current. Therefore, if the working pressure of the system causes a change in voltage, then the current will also change accordingly.

Conclusion

In summary, the relationship between conductor strength and system working pressure is relatively complex, and it depends on various factors, including the material, thickness, electric field intensity of the conductor, as well as the working conditions of the system. Without more context information, we cannot directly draw the conclusion that "conductor strength should be greater than the system working pressure." If specific numerical comparisons or analysis under certain conditions are required, detailed calculations and experimental studies are needed.
