at the point where the stream ofparticles breaks up. In some cases the stream of particles is a fine jet of waterissuing from a long nozzle attached to an insulated vessel, thevessel is connected with an electrometer, which thus measuresthe potential of the air; if it is wished to obtain a… … Fig. 59. 100 ELECTRICITY [CH. VI The motion of the spot is parallel to the axis of the drum,at right angles therefore to the motion of the paper. The trace of the spot when developed forms a continuouscurve, which gives the variations of the potential. Such acurve obtained at the National Physical…
