t the leaves of the electroscope diverge.Negative electricity is discharged from the point (780) until its potential isequal to that of the surrounding space. When equilibrium is established, theelectroscope indicates the potential of the point and, therefore, of the space inits neighbourhood. If… … Thus the electroscope shows the changes in potential of the space roundthe point. In stormy weather the potential may be considerable, and asthe bar can then give dangerous shocks, a metal ball must be placed near itwhich is well connected with the ground, and which is nearer the bar thanthe…
