A new method for the absolute measurement of resistance
Year: 1909
A new method is suggested for the absolute measurement of resistance. A revolving coil, or 2 such coils, are to be so disposed in the magnetic field of a pair of fixed coils as to yield an e.m.f. which can be compared, by means of a differential galvanometer, with the fall of potential through a fixed resistance, and so give the absolute value of the resistance. The advantage of this method would be that the e.m.f. generated could be a thousand times greater than in a Lorenz apparatus, while the thermoelectric forces at the sliding contacts would be considerably less; for a revolving coil cuts the lines of force four times in each revolution, and two coils o
