Dear Forum,
Hello all, this is my first post. I'm trying to teach myself EE enough to design basic circuits and play with microcontrollers (my background is computers, programing, and, um, music). I've started reading The Art of Electronics and many Internet sources but I seem to be missing something fundamental. I'm hoping that someone can point me in the right direction.
If V = IR (Ohm's law) then why does the voltage from a non-ideal voltage source droop/sag when then current draw of the load increases? Such as the fairly generic linked graph shows:

Thank you very much in advance,
Noob
