Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1877 edition. Excerpt: ... the needle of the torsion electrometer is immediately deflected. tThe electricity therefore resides in the outer surface of the ball. Experiment III.--Repeat the experiment with a basket of wire or wire gauze, supporting the cage work on an insulating tdble, or by means of the glass handle (Gr, fig. Kg. 82.--Showing mode of 83). The electricity will still be testing interior of Hol-found resident on its outer surLow Electrified Ball, by face. means of Troof-plane. Experiment IV.--Place a metal ball, or any good conductor, in the metallic cage (H B N, fig. 83), and hold it, by means of the glass handle (G), to the prime conductor of the machine at Q work. It will be found im ' possible to charge the contained body, though the outside of the wire cage, when tested, maybe shown to be powerfully charged. In this case the contained ball must be smaller than the interior of the vessel, so as to lie below its upper edge. Experiment V.--1. 83.--wire Basket, HBK with Glass Handle, G.

Bring a solid brass ball (B), in size and other respects exactly similar to the first, into contact with the first ball. The second ball is to be insulated, but not electrified. After being brought into contact with the first, it will be found, on carefully testing with the torsion or Thomson's quadrant electrometer, that the second ball has removed exactly one-half of its charge from the first ball--the charge of the latter dividing itself equally between the two balls. 3. Kepeat the above experiment, now using in place of the solid a hollow brass ball, insulated and in every other...show more
