What reading level is Selenium Cells book?
To quickly assess the difficulty of the text, read a short excerpt:
TO TESTING SET TELEPHONE INDUCTION COIL FIG. 14. CONNECTIONS FOR BUZZER AND INDUCTION COIL TO PRODUCE ALTERNATING CURRENT A small two point battery switch and four double spring binding posts are also mounted on the base and wired as shown by the dotted lines. A fairly sensitive galvonometer is em- ployed to indicate when the bridge is balance. A telephone receiver might be used for the pur- pose, opening and closing the circuit to cause TESTING AND MATURING 37 clicking in the receiver, the bri...dge being bal- ance when the noise is reduced to a minimum. The small center zero ammeters with the shunt removed make excellent galvonometers.
Ratio arms and a rheostat box having a max- imum resistance of 100, 000 ohms complete the apparatus necessary to make the tests on the cells. A laboratory set with this range is rather expensive and since our measurements need not be extremely accurate a good resis- tance box may be made from resistance units as used for motor starting and signal work. These units consist of an iron tube covered with asbestos on which is wrapped the resis- tance wire, the wire in turn being covered with a vitreous insulating material baked in place.
