unknown resistance whosevalue has to be determined is small. Instead of dividing the current fromthe battery E between the two coils,I join up the coils, so that the samecurrent passes through both of them,and by reversing one of the coils, g,prevent the current from influencingthe needle (see Fig.… … 14 ELECTRICAL PAPERS. currents in g and g are equal; but should r not equal rr, there will bea greater current in one coil than in the other, and the needle willmove in obedience to the difference of these currents. It then onlyremains for me to show what, and under what circumstances, advan-tages…
