Hello All.
I am new to electronics, can anybody help me about some questions?!
First i want to know how the voltage in output of U1 gradually increases till D8 turn on?
And my second question is about the current limiter; in fact i read the explanations but i wonder if some body explain more about how it work...
I'm sorry for my stupidily questions...

Many thanks,
