I thougth I had posted a response, but I can't seem to locate it. Your calculatins are correct.Originally posted by Hurdy@Mar 16 2006, 11:45 PM
I calculate this.
V = 5.5
I = 40ma
5.5 / (40x10^-3) = 137.5 ohms
I take it I have to take away my coil resistance from this?
137.5 - 125.7 = 11.8 ohms
Is this how you do it?
