Just wondering if you guys could give me some theory as to the operation of a solenoid.
Dealing with 24Vac irrigation solenoids, and long runs of wire we deal with some different siturations.
From what I understand. Voltage and current are proportional to each other when it comes to inductors. If voltage goes up so does current, and if voltage goes down so does current. Opposite from what ohms law states dealing with resistance.
Now if you were to drop the voltage to some dangerously low level, you will no doubt lose electro-magnetic energy, but if the voltage is not low enough to keep the solenoid from closing, how would that affect the solenoid? Would it heat up even though there is less current? Or do something else?
From my understand that if the solenoid plunger did not move and close the air gap the current would stay higher than if the plunger did move. Perhaps not as high as the initial inrush current would be, but higher than the holding current would have been. Is this true?
Thanks for any help.
