... be insulated. 7. When electrification is excited by friction or by any other process, equal charges of positive and negative electricity are always produced. To show this, when the electrification is excited by friction, take a piece of sealing- wax and electrify it by friction with a piece of flannel ; then, though both the wax ... area pars 80 that -W -$ - = area pqrs (2), sinc...
