A lot of RF Cafe visitors might
not be familiar with some of the electronic devices presented in this Electrochemistry
Quiz by Popular Electronics' resident quizmaster, Robert Balin (a big list of his other
quizzes is at the bottom of the page). I offer my assistance. A is a photocell,
B is an early type of rectifier, C is a varistor, D is a cathode ray tube (CRT), E is
an electrolytic capacitor, F is a heated cathode in a vacuum tube, G is a flashlight
battery, H is an early receiver crystal detector, I is a magnetic audio recording tape,
and J is phonograph cartridge. I scored 60% - sad.
By Robert P. Balin
operating characteristics of many electronic components are directly dependent on the
chemical properties of materials used in their manufacture. Test your knowledge of chemistry
by matching the chemicals (1−10) listed in the column at right with the sketches (A−J)
of the electronic components in which they ore used.
1 Aluminum oxide ___
2 Barium titanate ___
3 Cadmium sulfide ___
4 Cuprous oxide ___
5 Ferric oxide ___
6 Lead sulfide ___
7 Manganese dioxide ___
8 Strontium oxide ___
9 Silicon carbide ___
10 Zinc sulfide ___
See answers below.
Popular Electronics published many quizzes over the years
- some really simple and others not so simple. Robert Balin created many of the quizzes.
