DussanR:
but what i mean is if my power supply is 12V at 2A. there's no chance of it damaging the circuit? it will only draw the 1.1 to work for the whole circuit?
No there isn't.
Look at a car battery, it is rated to supply over 100A to turn the starter motor, yet you can still just run the interior 1/2A light off it on its own.
The power supply delivers constant output volts until the current being drawn by the load, meets and exceeds its rated current rating.
