205. What does the electronic symbol of figure «9» represent
The symbol in figure 9 represents a triac thyristor, a three-terminal bidirectional AC switching device with terminals MT1, MT2, and a gate (G). This configuration distinguishes it from diac trigger diodes, rectifier diodes, and zener diodes, which are all two-terminal devices.
