KitsGuru Diode as a Reverse Current Blocking Element LGSK006 Educational Electronic Hobby Kit

Diodes are semiconductor devices which allows the current through them only in one direction. The property has many applications in electronics devices. For example in AC to DC conversion, the diodes are used. It can also be used in protection circuits. Here we have demonstrated the concept by using LEDs as they also are diodes(LED=Light Emitting Diode). In the given circuit diagram, as we turn on the switch (s1) the LED D1 glows as it is connected in forward direciton and LED D2 doesn't glow as it is connected in reverse direction. As we change the polarity of the battery, we can see the opposite result.
