is then 7. l3 + aa = l3 — tx - l2. i is the correction that must be added to the potentiometer readings,t may be either positive or negative. Expt. 206.—Zero error of potentiometer. Place two resistance boxesB and BC (Fig. 831) in series with a Daniells cell; with 50 ohms inB and 100 ohms in BC,… … Expt. 207.—Comparison of re-istances by potentiometer. ForIhe comparison of low resistancesIhe potentiometer is convenient.roin the two low resistances ABLnd CD in series, and pass aurrent through them (Fig. 832).I the resistances are 0 1 ohm>r less, at least 1 ampere shouldpe employed.
