influencing cylinder. In this instrument the energy of the result-ing electric field is drawn from that of the falling diops. It is instructive to calculate the law of increase of charge.Let V be the instantaneous potential of the system ab ; and Vthat of the system ab ; let c be the capacity of a… … Fig. 57. leakage of each {i.e. I = Since the charge on each drop inside a isab in time dt is -ncVdt-lVdt, and the corresponding increase of potential is this quantity dividedby C. Similarly for the system ab the increment of potential is ncV nnl dV= (Subtracting we obtain d{y whence by integration…
