e cell may be used. Itse.m.f. is so near one volt as to be usable as such.A number of Daniel cells carefully set up and con-nected in series may be measured as to e.m.f. andthe reading used for tests. But for accurate work the Clark or the Westoncell is necessary. 38 ELECTRICAL INSTRUMENTS. The… … Fig. 25, The Weston cell, Fig. 25, has a positive elementof mercury also, but the negative element is cad-mium amalgam in a saturated solution of cadmiumsulphate. Its e.m.f. is 1.019 volts. The actual construction of standard cells maybe found in any of the large works on testing. CHAPTER IV.…
