I understand maximum power transfer happens when the source and load have the same impedances.

Subject: vertical sensor

Hi All,  I am moving right along on the small vertical spring sensor I am building.  At this point I would like to ask two 

1.  I have made an adjustable magnetic damper, which I can slide in and out to increase or decrease the effect.  Chris, gave me a 
very good example of how to adjust the damper on the Horz Lehman, I finished a few months ago.  It was something like, "move the arm 
10mm and release it, it should move past center and extend 5mm past center, it then should return to center and stop;"   Would it be 
the same for a vertical spring sensor?

2.  The coil measures 847 ohms.  If I were to use a resistor to act as a damper, what would the ohms value be for the resistor?
     Is there a formula?

Thanks, Ted
