| Description |
Maxwell's bridge method was employed, a rotating commutator of special design being used to charge and discharge the condenser. The first portion of the paper is devoted to a consideration of the formula for the capacity, the object being to make the correction factor as small as possible. The usual stroboscopic device for maintaining a constant speed was abandoned; in its stead the observer at the galvanometer telescope controlled the speed of the driving motor by observations of the galvanometer deflection, the number of revolutions of the commutator and the beats of a chronometer being simultaneously recorded on a chronograph. The average variation in speed was about 1 part in 25,000, and the error in the result due to such variat Subjects: measurements and use of instruments; Electrical instruments and techniques |
