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. 1878 edition. Excerpt: ...4. (a.) Can you see any connection between electric induction and the fact that electricity dwells only upon the outer surface of a conductor 1 (6.) Describe the plate electric machine, (c.) Explain its action, (d.) Explain the action of the electrophorus. 5. (a.) A minute after the discharge of a Leyden jar, a second and feebler spark may generally be obtained. Explain ( 356.) (6.) State two uses of lightning-rods. 6. (a.) Having a metal globe positively electrified, how could you with it negatively electrify a dozen globes of equal size without affecting the charge of the first? (6.) How could you charge positively one of the dozen without affecting the charge of the first 1 7. Can you devise a plan by which a series of Leyden jars, placed upon a glass plate, may be simultaneously charged, the first positively, the second negatively, the third positively, the next negatively, and so on 1 Recapitulation.--In this section we have considered the Condensation of electricity; the Leyden Jar; the Leyden Battery; the Distribution of electricity on conductors; Atmospheric Electricity; electrified Clouds and Lightning; Lightning Rods and their action; the Velocity of the electric current and the Duration of the electric spark; six Classes of Effects of electricity and many electric experiments. VOLTAIC ELECTRICITY.--DYNAMO-ELECTRICITY AND THERMO-ELECTRICITY. 373. Chemical Action.--All chemical changes produce electric separation. This is true whether the substances subjected to chemical action be solid, liquid or aeriform; but the chemical action between liquids and metals gives results the most satisfactory. Electricity thus developed is called Voltaic or Galvanic electricity. 374. The Electric Current.--When a strip of copper and one of zinc are...show more
