Hi guys! In this video, I will explain the basic structure and working principle of the optocoupler. Optocoupler is a circuit element that can control high currents with low currents without an electrical connection between two circuits and it provides electrical isolation to these two circuits. Thanks to optocouplers, different currents are isolated from each other and flow safely in the same circuit. As you can see in the figure, 4 and 6 pin optocouplers are widely used in different models. So, let's see how is the structure of the optocoupler?
