from The Century Dictionary.
- noun An alloy of 84 per cent. copper, 12 per cent. nickel, and 4 per cent. manganese, used, generally in the form of wire, to make electrical resistance-coils, since its resistance varies little with changes of temperature.
Sorry, no etymologies found.
Manganin can be obtained in sheets, and from this material standards of 10-2, 10-3, and 10-4 ohms are made by soldering strips between stout copper bars, and these are adjusted by gradually increasing their resistance by boring small holes through them.
