It is another name for a GFCI (Ground Fault Circuit Interrupter) which is the name used in North America for an RCD (Residual Current Device) as it is known in Europe and elsewhere in the World.

Which current is the leakage current that flows through a photo diode with no input in a light detector?
leakage current itself
What happend when a convection current detector came near a heat source?
When a convection current detector comes near a heat source, it will detect the movement of air or fluid caused by the temperature difference. This movement creates a convection current around the heat source, which the detector can measure to indicate the presence and intensity of the heat source.
Why is it important not to used Nicads in smoke detectors?
The battery in a smoke detector should last a year (though the detector should be checked monthly). The detector works on "trickle" current that is always there. NiCads will lose more current than an alkaline battery from just sitting around - much more. Even a fully charged NiCad will usually not last a year in a smoke detector. Alkaline batteries will easily.
Why the Americium is used in smoke detectors?
Americium is used in smoke detectors because it emits alpha particles that ionize the air, creating an electrical current. When smoke enters the detector, it disrupts this current, triggering the alarm. Americium has a long half-life, making it reliable for long-term use in smoke detectors.
How does a metal detector find the metal?
An alternating current is sent through the detector which creates an electromagnetic field. A piece of metal will disrupt this field and is detected by the magnetometer or another coil.
Why does the skin resistance go down and the current goes up when you lie to a lie detector?
because you sweat.
Which actinide is used in some smoke detectors?
The actinide used in some smoke detectors is americium-241. It emits alpha particles, which ionize the air inside the detector, causing a small electric current to flow. When smoke enters the detector, it disrupts this current, triggering the alarm.
What is the difference between detector and diode detector?
difference between detector and diode
Where and how is americium used in the home?
It's used in smoke detectors. It ionizes the air in the detector, and the electrons displaced by the ionization flow between two plates. Smoke disrupts this flow, the detector sees the change in current as proof of a fire and sounds the alarm.
What does americium do in smoke detectors?
Americium-241 is used in smoke detectors because it emits alpha particles that ionize the air inside the detector. This ionization process allows a small electric current to flow between two electrodes in the detector. When smoke enters the detector, it disrupts this current, triggering the alarm.
What type of radiation detector works when a charged particle ionized a gas that allows a current to flow and causes a speaker to click?
geiger counter
How you find unknown inductance in Maxwell bridge?
first see that there is no current passing through detector and balce it z1 Z4= z2 z3
