Assalam o alaikum,
I have been digging up many threads to find myself information regarding Building up a variable power supply 0-32Vdc and 3-4.5Amp(5amp). And found this thread to be more easy rather others.
So here are my following questions with reference to post # 5 @sgtwookie:
1.You said
2.Regarding the power dissipation at low voltages we have to use the tapped voltages from the transformer so can you please guide me how can we do it...by simple means of switching or using the 0-12v input into another circuit with it.
Also i m posting the circuit constructed by me on proteus oif u can help me with this circuit,it will be highly appreciable.
Others are also welcome to give suggestions
Regards,
Asad

So by any means we cannot regulate the voltages by using 5k-10k variable resistor(potentiometer)?Let's say just for example that you have a reasonably stable 35v on your filter capacitor after rectification, and it'll stay within a few volts of that whether your regulator is putting out 10mA or 5A
