Rachel Anne's articles Silicon Controlled Rectifier Silicon Controlled Rectifier Definition A Silicon Controlled Rectifier is a 3 terminal and 4 layer semiconductor current controlling device. It is mainly used in the devices for the control of high power. Silicon controlled rectifier is also sometimes referred to as SCR diode, 4-layer diode, 4-layer device, or Thyristor. It is made up of a […] December 18, 2021December 18, 2021 Saving Bookmark this article Bookmarked Difference between photodiode and phototransistor One major difference between the photodiode and the phototransistor is that photodiode consist of a normal P-N junction diode which a transparent window through which light can fall inside whereas in phototransistor uses a transistor which controls by exposure to light. This article is about photodiode vs phototransistor and also the comparison between the photodiode […] December 7, 2021December 7, 2021 Saving Bookmark this article Bookmarked Oscillator Circuits Energy needs to move back and forth from one form to another for an oscillator to work. You can make a very simple oscillator by connecting a capacitor and an inductor together. If you've read How Capacitors Work and How Inductors Work, you know that both capacitors and inductors store energy. A capacitor stores energy […] November 10, 2021November 10, 2021 Saving Bookmark this article Bookmarked Series resistors Components are in series if they are joined end to end like this: The last article covered the resistor differences between series and parallel.

An optocoupler or optoisolator, is a device that contains a light-emitting diode (LED) and a photosensor ( photodetector, such as a photoresistor, a photodiode, a phototransistor, …etc ). The purpose of an optocoupler is to transfer signals from one circuit to another yet keep them galvanically isolated. Here I want to show you how to […] October 6, 2021October 6, 2021 Saving Bookmark this article Bookmarked What is the role of the capacitor in the power circuit? The capacitor is composed of two conductive parallel plates, a passive device that stores energy in the form of an electric field, and releases the stored energy out of the circuit when needed. Capacitors are divided into bypass capacitors, decoupling capacitors, filter capacitors, etc., which are often used in power circuits. When the function of […] September 1, 2021September 1, 2021 Saving Bookmark this article Bookmarked Are Sensors Useful for Vehicles? Automobile sensors are the input devices of the automobile computer system, which can keep the engine in the best condition, and there are many kinds of automobile sensors.

The function of A/D conversion is to convert analog signals with continuous-time and continuous amplitude. It is converted into a digital signal with discrete-time and discrete amplitude. Therefore, A/D conversion […] June 11, 2021June 11, 2021 Saving Bookmark this article Bookmarked
