What is the typical outcome of having a poor electrical connection?

A poor electrical connection often results in increased resistance at the point of connection. This resistance can lead to an elevated temperature due to the energy loss in the form of heat, which creates a significant risk of overheating. Such overheating can not only damage the wiring and connected components but also poses a serious fire hazard. Equipment connected to a poor electrical connection may operate inefficiently or erratically, leading to potential malfunctions or complete failure. Therefore, recognizing the importance of maintaining good electrical connections is crucial for safety and performance in electrical systems.
