galvanometer (whoseresistance is known) is connectedin shunt with a resistance-box i2,as in Fig. 47. With no resistancein R adjust R1 till the tangent gal-vanometer gives a deflection ofabout 45°, then adjust the resis-tance R to obtain the deflections of5, 10, 15, etc., scale divisions on the… … Fig. 47. ELECTROMOTIVE FOBCE. 95 ELECTROMOTIVE FORCE. Exercise 50. — Determination of electromotive force by themethod of comparison. Join the cell to be tested in series with a gravity-cellwhose electromotive force is known, a resistance-box, anda galvanometer. Introduce sufficient resistance to…
