Triacs – Working and Application Circuits
A triac can be compared to a latching relay. It will instantly switch ON and close as soon as it’s triggered, and will remain closed as long as the supply […]
Understanding Crystal Oscillator Circuits
Crystal oscillators are electronics devices that produce stable, accurate, and repeated signals that are widely employed in a wide range of electronic applications. Because of their great stability, precision, and […]
SCR Applications Circuits
In this article I have explained many interesting SCR application circuits and also learn the main features and properties of an SCR also called a thyristor device. What’s an SCR […]
Comparator Circuits using IC 741, IC 311, IC 339
The basic function of a comparator circuit to compare two voltage levels at its input pins and produce an output to show which input voltage has higher potential than the […]
