Overloading amperage? Answered
If I have a device that is rated at max 17 amps and 31.5 volts (but capable of operating at any lower amperage or voltage) and I want to run it off a 12v 7amp circuit, will that overload my circuit? Do I need to put a resistor in to limit the load?
What if I need to bring the amperage down to 3.47 amps off the 7 amp circuit... do I need to put in a resistor then, or will my power supply just automatically supply only what it can?
