Hello guys, I'm going to explain semiconducting components in electronic circuits, in particular, diodes and LEDs.

2
00:00:09,789 --> 00:00:14,910
Both of them are active components. They modify the flow of the current.

3
00:00:15,609 --> 00:00:21,030
A diode has two electrodes, anode and cathode.

4
00:00:21,429 --> 00:00:29,190
These electrons only allow the current to flow in the anode-cathode direction, but not the reverse.

5
00:00:29,190 --> 00:00:34,189
In this case, it will behave like an open switch.

6
00:00:34,770 --> 00:00:35,929
Look figure 6.

7
00:00:37,250 --> 00:00:44,729
An LED light-emitting diode is a diode that can emit light when a current flows through it.

8
00:00:45,270 --> 00:00:51,189
We must always connect a resistor in series alongside an LED to protect it.

9
00:00:52,530 --> 00:00:54,250
Now it's your turn.

10
00:00:54,250 --> 00:01:05,469
In the computer, go to Crocodile Clips and design this circuit and put four legs in a way that only legs in position 1 and 3 can light.

11
00:01:06,469 --> 00:01:11,689
Save here the task in the virtual classroom.

12
00:01:12,530 --> 00:01:16,930
OK, and your mark will be based on this evaluation tool.

13
00:01:17,969 --> 00:01:18,989
Good luck, guys!
