This quiz from Popular Electronics is a bit trickier than others because it requires you to
think abstractly rather than concretely. Quiz-maker Robert Balin presents a series of circuits
and components along with the first letters of the related topics. Your mission, should you
decide to accept, is to match the item to the letter. The example provided is matching the
letter 'J' to a drawing of that type of half-wave antenna. I have to admit that my attempt
at matching all of the items and letters was taking a lot of time, so I quit before finishing
all of them; my hard head is better at concrete thinking.
Electronic Alphabet Quiz
By Robert P. Balin
The letters of the alphabet are often used as abbreviations for electronic terms. Thus,
J means to the electronics enthusiast a type of half-wave antenna. Can you match the letters
below with the drawings (1-10) of the devices and circuits to which they most logically refer?
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.

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
