Voltage
The Voltage is described as a thrust behind the electricity. Stress can be too referred to as potential difference, electromotive force (EMF) or electrical pressure. Imagine electricity as water flowing…

What is a diode for a doorbell?
Doorbell diode The included diode with your video ringing ring is used to connect the device to a digital sound of the sound. Digital sound signals are usually a speaker…
Why is 194 db the loudest sound possible?
The lower audibility limit is defined as SPL of 0 dB, but the upper limit is not as clearly defined. While 1 atm (194 dB Peak or 191 dB SPL)…
What is the loudest sound on earth?
The most powerful sound in the world. The sound of the Krakatoa volcano eruption in 1883 was so intense that it had broken the ears of people 40 miles away,…
What is an open loop gain?
The gain in an open loop of an amplifier is the gain obtained when no global feedback is used in the circuit. The increase of the open loop in some…
What is the difference between NPN and PNP proximity sensors
PNP sensors are sometimes called “supply sensors,” because the power supply is positive at the output. NPN sensors are called “diving sensors” because they sink at the exit. NPN and…
What is the difference between NPN and PNP transistors
Here i write in single line difference between NPN and PNP Transistor. full review will be added in later post. NPN transistor NPN transistor is the type of p-type bipolar…
What is a rail to rail amplifier?
Analog Devices High Speed Optics (> 50 MHz) Analog Devices Rail-to-rail assemblies allow you to work with lower supply voltages, approach the tracks and provide a wider dynamic range. Equipped…
What is a refractive index detector?
The refractive index (RI) is the only universal detector in HPLC. The detection principle involves measuring the variation of the refractive index of the effluent from the column passing through…
How does an infrared detector work?
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic (photodetectors). The thermal effects of incident IR radiation…
What is the use of IC lm358?
The LM358 is a dual-core, dual-core, low-power operational amplifier, originally initiated by National Semiconductor. It is used in detection circuits. The LM358 abbreviation indicates an 8-pin integrated circuit that includes…
How does a photodetector work?
A photodiode is a semiconductor device with a p-n junction and an intrinsic layer between layers p and n. It produces photocurrent in the generation of electron-hole pairs due to…
What is the role of a LED in a circuit?
In electronics, an LED circuit or an LED driver is an electrical circuit used to power a light emitting diode (LED). The circuit must supply enough current to illuminate the…
