An electromagnetic relay in its switching principle is a mechanical switch which is operated with a low-power DC voltage. The switch part is used to control high power circuits.
When it comes to experiment with colorful LEDs, students finds it very interesting in using them to build electronics circuits to indeciate current. Because its a priority to use realistic graphics with…
