Hi everyone
I know it's a very noob question, but nobody could explain me the concept clearly, and to make things worse I love electronics, but my Math is really dumb.
How can the current be regulated? I know IC's to regulate the voltage, and (as far as I know) the current depends of the load connected to the circuit. But how can the Power supply of the picture regulate its current?
(I put a link, because the picture is too big)

The same question applies to batteries. Another forum told me that battery chargers regulate the given current using a resistor, and its value is calculated using
V = I * R
V/I = R
I.e.: If my battery is 9 volt - 200 mA ----> 9 / 0.200 = 45 ohm?
I have the bad feeling Im making a veeery ridiculous mistake.
Thank you so much in advance
