electroscope's Usage Examples:

If, without removing the electrified body, the plate or knob of the electroscope is touched, the leaves collapse.

If an electrified body is held near the gold-leaf electroscope the leaves diverge with electricity of the same sign as that of the body being tested.

To detect electrification it is best to charge the electroscope by induction.

A third great use of the electroscope is therefore to detect electric conductivity either in the air or in any other body.

Radio-active bodies are chiefly recognized by the power they possess of rendering the air in their neighbourhood conductive; hence the electroscope detects the presence of a radio-active body by losing an electric charge given to it more quickly than it would otherwise do.

If the ball is discharged and touched against the other tray, and then afterwards against the previously charged electroscope, the leaves will collapse.

If an insulated brass ball is touched against the first tray and then against the knob or plate of the electroscope, the gold leaves will diverge.

The sign of the electrification imparted to the electroscope when so charged - that is, whether positive or negative - can be determined by rubbing the sealing-wax rod with flannel and the glass rod with silk, and approaching them gently to the electroscope one at a time.

condenser plate P attached to the outer case, then this substance bestows conductivity on the air between the plates P and P', and the charge of the electroscope begins to leak away.

The electroscope was used in conjunction with an oil lamp or gas flame.

electroscope's Meaning':

measuring instrument that detects electric charge; two gold leaves diverge owing to repulsion of charges with like sign
