>> Could this be a good Tip..: ,,Run Zener's (in all cases of sizes /zenerVoltages) to around 20mW - 60mW. ,,Say fex..

In addition to running the Zener at a sensible current choose a 5v1 Zener as these usually have a near zero temperature coefficient. Lower voltage Zeners have an increasingly negative temperature coefficient and higher voltage Zeners have an increasingly positive temperature coefficient.
Also add a 10uF decoupling capacitor across the zener. Could add a series diode as well as a crude temperature compensation measure. It will increase the voltage slightly if the potentiometer is reconnected across the zener and diode together with the decoupling capacitor.
Very clear and helpful, thank you.
I need a good power supply. wanted to make myself to save money. I dont have to do the experiments now. Thanks a lot.
I always find it useful and informative ❤
Very interesting video, thank you.
Thank you soo much sir for this lesson
Great video. Thanks
I'm learning alot.
From 24:20 it's like an eye operation!
You are save my job🎉
Nice. Are you going to cover current regulation?
👏👏👏👍👍👍
