Electricity and magnetism for advanced students (1920)
Starling, Sydney George, 1873- · London Longmans, Green · leaf 173
to exactly half, showing thatthe capacities were no longer equal. Thus, ifVj is the originaWpotential of A, and Vg thefinal common potential, the original potentialof B being zero, calling C„ and Oj the capaci-ties of A and B— The charge passing from A to B, that isq = C«(V, - V,) = C,V„ Cfi V,-V.… … Fig. 174. 1-50 = (^ + 1)2 which gave ^ = 2 for shellac. In a similar manner Faraday found the dielectric constant ofsulphur to be 2 2. A considerable improvement in the comparison of capacities by theabove method may be made by using the electrometer instead of theelectroscope, but in this case the…
