Funny that more than half of the video's script was exactly the same as the wikipedia article on optocouplers. Word for Word. see for yourself: en.wikipedia.org/wiki/Opto-isolator

In circuit board when you connect the anode and cathode to the left side of the optocoupler and the led with the transistor all in left side ,what are you going to connect to the right side of the optocoupler?

What's with the narration of this video? It totally sounds like it's a synthesized voice. It reads exactly what's in the text, including the incorrect grammer, yet pronounces the component parts correctly.
