Zener & Transistor as Voltage Regulator & circuits

As an electronics engineer, you've probably needed a constant, unchanging voltage in your circuits and experienced the use of a voltage regulator.
To have a regulated and constant voltage instead of the heavy costs of the power supply, use a voltage regulator to meet your needs at a low cost.
In this video, we are trying to learn about these types of circuits and their advantages and their important types.
In the previous videos, we noticed that the DC output voltage of half-wave or full-wave rectifiers has some ripple that is placed on the DC voltage, and as the load value changes, the average output voltage also changes. By connecting the zener stabilizer circuit in the rectifier output, a more stable output voltage is produced....
