What effect does corrosion have on electrical connections?

Corrosion significantly reduces the efficiency of electrical connections. When metal surfaces corrode, a layer of oxidation or rust forms, which acts as an insulator rather than a conductor. This diminished contact area and poor surface quality lead to increased resistance within the connection. As a result, less current can flow through the corroded area, and the overall performance of the electrical system declines. This issue can lead to poor operation of components and can even result in complete failure if not addressed, making corrosion management essential in maintaining reliable electrical connections.
