What can excessive electromagnetic interference lead to in electrical systems?

Excessive electromagnetic interference (EMI) can significantly disrupt the normal operation of electrical systems, leading to operational disruptions or malfunctions. EMI can cause devices to behave unpredictably, leading to erroneous signals, data corruption, or complete failure of equipment. This is particularly critical in sensitive electronic devices that rely on precise electrical signals to function properly.

For instance, in communication systems, EMI can introduce noise into the signals being transmitted, resulting in poor quality or loss of communication. In industrial settings, where machinery relies on electronic control systems, EMI can result in incorrect operations or even safety hazards. Overall, while the presence of EMI does not lead to improved performance or lower energy consumption, it poses significant risks to the reliability and efficacy of electrical systems.
