I want to control multiple 5V 0.2A fans by PWM (Like here) and want them to share a common power supply. I have a little bit of trouble understanding the following:
If I have, for example, 3 fans and a 0.6A power supply and there is a scenario where just one fan is on (with PWM full on), isn't this one fan getting the 0.6A of current? Or does the fan just draw 0.2A of current even if 0.6A are available?
Thanks in advance
