Definitions
- Fign rel represents a rheostat or artificial resistance. Itmay be of any convenient or coma'certain number of coils, B C, whichare here shown as wound on or supported by bars or rods D D. The whole numbcr'of coils may be inserted in a given circuit in series, or'auy one or more pairs of I them may be so inserted; but however the coils may be used with a rise of temperature, while theother 1 portion ,is often alioyql he re described above.
- FIG. 2 is a form of magnet. suchas might be used in electrical regulators to-preserve the resistance 'of the coil; constant. They are made partly of oncol' the ordinary-metals -or alloys, such part ngl dcsig ter E, and partly of "the alloy above described,
- An electrical conductor composed of an alloy of sixty-five to seventy parts copper, twenty-five to thirty parts ferromauganesc, and two and a half to ten parts nickel.
- An-electrical conductor consisting of two metallic portions, the jni nt electrical resi stance of which remains substantially constant under conductor the elecdimiuishes with in conductor consisting of an its equivalent, manganese,
- a conductor consisting of two metallic portions, one composed of a material the electrical resistance of which increases with an increase in its temperature, and the-other composed of a material the electrical resistance of under similar conditions, as and for the purpose specified.
- a conductor consistin' portions,'one of which is composed of a material the electrical resistance of which increases with anincrease in its temperature, and the othcr'is composed of an alloy of copper or its cquivalentnnangancsc and nickehas set forth.
