This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1915 edition. Excerpt: ...scale, together with a small mirror mounted on the moving system of the instrument. The image of the scale in the mirror may be read by means of the telescope and, as the mirror turns, the part of the scale visible through the telescope changes. The deflection of the moving system, as read on a curved scale, will always be twice the actual deflection. If a straight scale is used, the readings on the scale, due to a given movement of the coil, increase in value with an increase in deflection, due to the fact that the ends of the scale are farther from the mirror than the center. The Ballistic Galvanometer.--The ballistic galvanometer is a form of galvanometer having a comparatively heavy moving system, which results in the galvanometer coil not moving from its zero position, or position of rest, immediately after it is connected to a source of electrical pressure. As a result of this property of the galvanometer, it is possible to almost completely charge or discharge a condenser through it before the moving system has moved appreciably from its zero position. In such a galvanometer, the deflection is produced in a manner similar to the action of a rifle bullet striking a suspended weight. The energy of the bullet is imparted to the weight which causes it to deflect and come to rest at an extreme position. When the weight comes to rest in its extreme position, the energy imparted to it has all been used in overcoming the action of gravity, as the weight is now in a higher position than when at rest. In the ballistic galvanometer the energy of the charge is imparted to the moving system and causes it to revolve against the action of a spring or suspension until the energy of the quantity is all stored in the spring or suspension. The moving...
