Question: 1 / 400

If both materials are conductors, what happens to the electrons?

They remain static

They move rapidly

When both materials involved are conductors, electrons can easily move between them due to the presence of free electrons in conductive materials. This high mobility of electrons allows them to move rapidly, especially when subjected to an electric field or potential difference. The movement of these electrons is a fundamental characteristic of conductors, which facilitates the flow of electric current. In scenarios where conductors are connected or in proximity, electrons will redistribute themselves to equalize electric potential, further contributing to their rapid movement. This behavior is essential in various applications, including electrical wiring, circuit design, and understanding conductivity principles. The concept of rapidly moving electrons is crucial to the functioning of most electrical systems.
