Using several online coil inductance calculators they all give me the wrong answer.
My original coil is, 8 turns, 1" diameter, 1.5" long, wound with #10 copper wire. Wire diameter is .125". Coil diameter is measured center line to center line of the wire. My meter reads .799 uh which is what I want target is .8 uh. Online calculator is telling me, .820, .821, and .820 uh.
My new coil is, 8 turns, 1.250" diameter, 2.875" long, wire diameter is .250"copper tubing, coil diameter is measured center to center like before. My meter reads .850 uh. Online calculator says, .727, 727, and 727.
I am trusting my meter to be correct. I was trying to use online calculator to wind the correct coil on the first try and not have to wind a dozen wrong coils to get it right.
I assume the circuit will see any .8 uh coil the SAME even if the coils are different shapes or sizes?
