Two discharge knobs, P and Q, (Fig. 895), are connected to thecollectors, and on the difference of potential between… … Fig. 897.—The Wimshurst influence machine. collector. Their function is to increase the capacity so that agreater accumulation of charge takes place before the difference ofpotential between P and Q, is sufficient to cause a discharge. Thedischarge will then be much more violent than when only a…
