Socket-outlet, auto switched by plug insertion. Automatically switched socket-outlets such as these may be used to supply power to refrigerators, some computers and other accessories that normally should not be switched off. The absence of a user operable switch prevents the accidental switching off of such devices Surface socket-outlet and plug.
resistors: the braking resistors of electric trains, used to dissipate electrical power when the catenary is not receptive during braking, can make electromagnetically induced acoustic noise; coils: in magnetic resonance imaging, "coil noise" is that part of total system noise attributed to the receiving coil, due to its non-zero temperature.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device that interrupts an electrical circuit when the current passing through a conductor is not equal and opposite in both directions, therefore indicating leakage current to ground or current flowing to another powered conductor.

Balanced connections see the spurious noise due to ground loop current as common-mode interference while the signal is differential, enabling them to be separated at the destination by circuits having a high common-mode rejection ratio. This rejection can be accomplished with transformers or semiconductor output drivers and line receivers.

The main difference between signal noise and emissions is that noise exists in a finite energy signal while emission exists in a finite power signal. As noise in measuring circuits gets filtered out using filters , the emission must be filtered at the device under test at either the AC mains or the DC mains, depending on the device application.
