Purpose of use
need critical inductance of 8H@300ma. I have on hand 20H, 8H, 8H, all 150ma, and same resistance.

Purpose of use
Check if 2 inductors in parallel halved because I have 2x 200uH inductors and I need a 100uH

Purpose of use
Cross verification
Comment/Request
I agree that the result is correct. but when it comes to ferrite inductors some claim that inductance will increase by the factor of four by making them in parallel.
