What is a common consequence of using a faulty relay?

Using a faulty relay can lead to equipment damage as a common consequence. A relay is an electromechanical switch that controls a circuit by opening and closing connections in response to incoming signals. If a relay malfunctions, it may not operate as intended, causing electrical signals to misfire or not reach their intended destinations. This malfunction can lead to excessive current flowing through components that are not designed to handle it, leading to overheating or failure of those components.

Additionally, if the relay fails to disconnect circuits when necessary, it could result in short circuits or overloads that can physically damage the equipment involved. Thus, the potential for equipment damage directly stems from the relay's inability to function properly, making this the most accurate consequence associated with using a faulty relay.
