What is one result of corrosion on an electrical connection?

Corrosion on an electrical connection primarily results in increased resistance. When metal surfaces corrode, they form an insulating layer of oxides and other corrosion products that impede the flow of electrical current. This added layer of material interferes with the conductivity between the contacts, causing resistance to rise.

Increased resistance can lead to several issues in electrical systems, such as excessive heat generation, reduced efficiency, and potential failure of electrical components. It's crucial to maintain clean and secure connections to ensure optimal performance and safety in electrical systems.
