atus with gas or water pipes. The charge of the leaves is proportional to their capacity and tothe difference of potentials V-V„ (51), where V is the potentialof the leaves and F„ that of the cage. The divergence, which de-pends on the charge, serves to measure either the charge or thepotential. If… … 82. Condensing Electroscope.—We have sometimes to deal with electrification which is very great as to quantity, but which isso distributed as not to produce a difference of potentials sufficientto cause a visible divergence of the leaves of an electroscope em-ployed as hitherto described. In such…
