mminThe distance between each "ridge" on the twisted wire. Use 0 for non-twisted wire (parallel strands). For improved accuracy: Count 10 ridges, measure their total width, and divide by 10.
AWG Ør mmin
mmin × mminThe width should normally be larger than thickness. Swap them
In a multi coil setup, all coils must be identical. Two coils in parallel. Total resistance is halved. (1⁄2 R) Two coils in serial. Total resistance is doubled. (2 R) All three coils in parallel. Total resistance is divided by three. (1⁄3 R) All three coils in serial. Total resistance is tripled. (3 R) All four coils in parallel. Total resistance is quartered. (1⁄4 R) All four coils in serial. Total resistance is quadrupled. (4 R) Two coils in serial, connected in parallel to a second pair of serially connected coils. Or the other way around: Two coils in parallel, connected in serial to a second pair of parallelly connected coils. Total resistance is the same as for a single coil. (1 R)
