In the context of conductors, thermal vibrations increase with:

Thermal vibrations in conductors are directly related to temperature. As the temperature of a material increases, the atoms within that material gain energy and vibrate more vigorously. This heightened activity is a manifestation of the increased kinetic energy of the atoms as they respond to the added heat. In conductors, these thermal vibrations can affect the flow of electrons, which is crucial for understanding electrical resistance and conductivity.

When temperature rises, these additional vibrations can lead to more frequent collisions between the electrons and the vibrating atoms, ultimately increasing the resistance of the conductor. This relationship between thermal energy and atomic motion is a fundamental concept in materials science and is essential in various engineering applications, such as circuit design and thermal management.

Other factors, like electrical voltage, humidity, and pressure, do not have a direct correlation to the level of thermal vibrations in conductors as temperature does.
