ANOTHER ALGEBRAIC BALANCE

N. J. Lennes · School Science and Mathematics · 1905

When the needle comes to rest, read the position to a tenth of a division.Then, without disturbing the galvanometer adjustment, replace the unknown resistance by a resistance box* divided to tenths of ohms, and find the deflections produced by each of two resistances differing by one tenth of an ohm, between which the unknown resistance lies.The hundredths of ohms can now be found by interpolation.If great sensitiveness is not desired, time may be saved by not weakening the control field so much.
