Ok, now I know how to calculate the resistance of a coil when you know the turns..etc etc. The situation is this.
I was checking the resistance of a solenoid for a numatics air valve. The resistance I got was much higher that I expected but contribute that to the inductive reactance. Other than taking a new valve and checking it's resistance for comparison, is there a way to calculate the actual resistance of the solenoid when you don't know the number of turns or the diameter of the wire.
At this time, I do not know what the voltage output of the Fluke 87 to be but I figure I will need that. The numatic valve ahs an operating current of .15 amps. I believe the resistance reading I got from the coil was approximately 165 ohms. I just want to be able to show, mathmatically, how I can get from the resistance reading to the running current reading. (ie: right now I come up with a current of 0.7 amps.)
I know I had this figured out a while ago, but have forgoten and I am sure I am just missing a fundamental theory reguarding inductance, but if someone can put it in lamens terms I would appreciate it.
Thank you for all your help.
