AI Thread Summary
Optodecoders, optoencoders, optocouplers, and optoisolators are essential components in electronic circuits that utilize light for signal transmission and isolation. Optodecoders and optoencoders convert optical signals into electrical signals and vice versa, enabling data processing and communication. Optocouplers provide electrical isolation between different parts of a circuit while allowing signal transfer, protecting sensitive components from high voltages. Optoisolators serve a similar function, ensuring safety and preventing interference in electronic systems. For detailed explanations and diagrams, resources like Wikipedia can provide comprehensive information.

I need detail explanation and if possible diagrams on optodecoders,optoencoders,optocouplers and optoisolators.

thank you.

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
