good day..
i had my power supply which i built last week and i want to add my 12vdc cooling fan..
if i have this schematic diagram below., how can i put my cooling fan, if my power supply is adjustable from 0-30 v, and my cooling fan must only be receive max of 12v dc.
any idea how to connect a resistor with my cooling fan?
