Hello all, I'm new in the field. I am familiar with the basic of Ohm's law and Kirchoff's laws but most knowledge I've gathered up until now is very basic. I want to build this Power Supply kit to practice soldering and perhaps get something practically useful out of it. I've been watching the reviews and build videos on youtube and one thing pops out. It's the (significant) voltage drops at certain current drawn. I tried to reason the cause behind the phenomenon but to my best effort, I can only note it down as due to an internal resistance of the power supply. But at different current ouputs, the internal resistance seems to vary. Could anyone please help me with this question?
Here are the two videos that I've watched that mention the voltage drops:
For the second video, the voltage drops are mentioned at around 3:00-3:05. The first video maker said that by removing the IC and some other components, the power supply has a higher current output and also, in the comment section, there are suggestions for an upgrade of transformer and diodes for better result output. Do you think it's a good idea as a project for a beginner like me?
Thank you for your time and answers. I hope this is not a silly question.
