Please excuse my ignorance - I am first and foremost a software person, and I only fool around occasionally with hardware...
I want to get 5-6 solenoid valves working in parallel. The solenoids are 12v DC, 500mA. I have a single 12v DC, 1A wall adapter. I would like to wire up the solenoids in parallel. To my understanding, with respect to voltage, it doesn't matter how many solenoids I have in parallel: Kirchhoff's law states that the voltage will always be 12v over each solenoid, even if I turn them all on at once. However, it is also my understanding that the current (amps) will be 'distributed' across each of the solenoids in parallel. That is, the 1A will be distributed across the N solenoids such that each has a current of 1A/N on it.
If I am understanding correctly, then, I would need a new 12v DC power supply with N * 500mA to adequately power all my solenoids?
EDIT: And as a more general question... What should I "watch out for"? Would too much current, or too much voltage damage the solenoids?
