What else can I help you with?
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.
How does ionization contribute to the functionality of a photoelectric smoke detector?
Ionization in a photoelectric smoke detector helps detect smoke particles by creating an electric current when smoke enters the detector chamber. This current triggers the alarm, alerting people to the presence of smoke and potential fire.
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?
In the smoke detector, the fast - moving alpha particles enable the air to conduct an electric current. As long as the electric current is flowing, the smoke detector is silent. The alarm is triggered when the flow of electric current is interrupted by smoke entering the detector.
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.
What happen when the convention current detector came near a heat source?
When a convention current detector comes near a heat source, it typically detects an increase in temperature due to the heat generated by the source. This change in temperature can cause a variation in the electrical resistance or current within the detector, potentially triggering an indication of the convection currents produced by the heat. As warm air rises and cooler air moves in to replace it, the detector may register changes in air movement or temperature gradients, providing insight into the convection process occurring around the heat source.
Why does the skin resistance go down and the current goes up when you lie to a lie detector?
because you sweat.
What is an current path detector?
A current path detector is an electronic device or system used to identify and monitor the flow of electric current in a circuit. It helps in detecting the presence of current, determining the direction of flow, and identifying potential faults or irregularities in electrical systems. Current path detectors are commonly employed in safety systems, industrial applications, and troubleshooting processes to ensure proper functioning and safety of electrical installations.
What creates the current in a smoke detector?
In a smoke detector, the current is created by a small amount of ionization that occurs when radioactive material, typically americium-241, emits alpha particles. These alpha particles ionize the air within the detection chamber, allowing a small electric current to flow between two electrodes. When smoke enters the chamber, it disrupts this ionization process, reducing the current and triggering the alarm. This change in current is detected by the circuitry, signaling the presence of smoke.
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
