What type of device is used to manage and limit electrical noise in circuits?

A surge protector is specifically designed to manage and limit electrical noise in circuits by absorbing and diverting excess voltage that can come from spikes in the electrical supply. These spikes can be caused by various factors, such as lightning strikes or sudden changes in power demand. By filtering out this electrical noise, a surge protector helps to safeguard sensitive electronic devices and maintains a stable electrical supply, which is crucial for their operation and longevity.

In contrast, fuses and circuit breakers are protective devices primarily focused on preventing overcurrent situations that can lead to overheating and potential fires. While they play an essential role in electrical safety, they do not address electrical noise. A transformer, on the other hand, is used to convert voltage levels in an electrical circuit but does not have the capability to manage electrical noise effectively. Thus, the surge protector is the most suitable choice for limiting electrical noise in circuits.
