About this product

Product Information

Excerpt from Radiotelegraphy: U. S. Signal Corps Electrical phemena may be grouped in two general classes, one of static electricity, when the electrical charges are at rest, and the other of dynamic or current electricity, when the charges are in motion along a conductor. When an insulator, such as sealing wax, is rubbed with far, or a glass tube with silk, it acquires the property of attracting light bodies near it, and is said to be charged. This action shows that forces exist in the adjacent space, and there is said to be an electrostatic, or, more briefly, a static field of force about the charged body. When two charged bodies are brought near together they may be either attracted or repelled, depending on the nature of the two chaises. If the rubbed glass is brought near particles touched and charged by the rubbed sealing wax they will he attracted to it, and similarly if the rubbed sealing wax is brought near particles charged by the rubbed glass they will be attracted; but two bodies, both of which have been charged by either the glass or the wax, will repel each other. Hence like charges repel each other and unlike charges attract. The names positive (glass) and negative (sealing wax) have been given, respectively, to these charges. By means of a delicately suspended insulated body the static forces can be mapped out along directions in general perpendicular to the charged surfaces.
