Prescott, George B. (George Bartlett), 1830-1894 · New York, D. Appleton · leaf 854
in fig. 632. Con-nect the terminals of both the standard galvanometer and the MEASUREMENT OF CURRENT STRENGTH. 837 galvanometer to be calibrated to two points in a circuit in wbiclia current is flowing—for instance around an incandescent lamp—or to the end of a battery. Kote the electro motive… … Fig. If, as before, the constant is represented by ^, the value E^of any other deflection o?^, in volts, will be El = ^ ^1, and for a tangent voltmeter In calibrating an instrument by this method it should be re-membered that the constant of the standard galvanometer maybe more or less altered by…
