Electronics Metals Quiz
|
|
This Electronics Metals Quiz appeared in the October 1964 edition of Popular Electronics. Given the era and obsolescence of some technologies, a couple of the drawings might not be recognizable to you. Accordingly, I feel obligated to clue you in on those. "B" is a television iconoscope, which was used in early TV video cameras. "D" is a phonograph stylus. For "F," keep in mind the prevailing semiconductor material at the time. "I" is a type of heater element that could be screwed into a light bulb socket (I used to have a couple). "J" is supposed to be a needle for a meter movement. Now that you know, have at it. The process of elimination should result in a good score. I got 10:10, but then I'm older than the quiz ;-) Electronics Metals Quiz
Various metals are used in making electronic devices. Can you match the names of the metals listed at left (1-10) with the drawings of components (A-J) utilizing their special properties? 1 Alnico ___ 2 Bronze ___ 3 Germanium ___ 4 Lead-Tin ___ 5 Cesium ___ 6 Tungsten ___ 7 Osmium ___ 8 Mercury ___ 9 Nickel-Cadmium ___ 10 Nichrome ___
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. This is a listing of all I have posted thus far.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
