To quickly assess the difficulty of the text, read a short excerpt:
which must be applied to produce maximum surface tension, as measured by the height of merciury in T necessary to bring the meniscus back to c, is also the contact difEerence of potential between the mercury and the electrol3rte. Suppose, now, it is desired to know the contact difference of potential between zinc and dilute sulphuric acid. The P.D. at the terminals E, Fig. 51, is the potential difference between the mercury and zinc. This can readily be measured by use of a potentiometer and is... evidently the difference between e' and e when these are both considered in reference to the same electro- lyte. For example, E is found to be 1.48 volts and e' is found by the capillary electrometer to be .86 volt. Then E'^e'-e 1.48 = . 86 -e .-. e=-.62 86 GENERAL PHYSICS. Thus the potential of the mercury is .86 volt higher than the electrolj^e, and the electrolyte is .62 volt higher than the zinc. In the voltaic ceU, Fig. 49, copper is .46 volt above the electro- lyte and the electrolyte .62 volt above the zinc.
