missouri100 Posted March 22, 2010 Report Share Posted March 22, 2010 I need to control the current to a solenoid in an automotive application. The input will be 12VDC and the output needs to be 12VDC. I need to vary the current to the solenoid from 0.1A to 1.1A. I am having trouble with the voltage drop in any circuits that I find. I would like to keep the overall current draw to a minimum. I can use a bunch of current limiting diodes in parallel and just switch them on and off as needed. Is this a viable solution?thanks for any suggestions Quote Link to comment Share on other sites More sharing options...
Hero999 Posted March 22, 2010 Report Share Posted March 22, 2010 You can't regulate both the voltage and current simultaneously.If you limit the current then the voltage will drop, see Ohm's law. Quote Link to comment Share on other sites More sharing options...
