Robert Balin created many
quizzes for Popular Electronics magazine back in the 1960s and 1970s. This
particular "Electronic Numbers Quiz" presents various objects and your challenge
is to match one of the provided numerical values to each item. For example, a tuning
fork is most commonly, in the Western world, associated with a certain frequency
for tuning musical instruments (electronic and mechanical). As is often the case,
being familiar with the "standards" of the era is helpful on a few of the items
like the tuning capacitor and the IF transformer, but you should be able to eliminate
some options by knowing the impedance of the twin lead transmission line and the
phase relationship of current and voltage in a pure inductance.
Electronic Numbers Quiz
By Robert P. Balin
Anyone in electronics gets to know many numbers, each of which relates primarily
to some specific circuit or component. Why not try your luck at matching the eight
numbers below with the drawings (A - J) to which they most logically refer?

See answers below.
Quizzes from vintage electronics magazines such as Popular
Electronics, Electronics-World, QST, and Radio News were published
over the years - some really simple and others not so simple. Robert P. Balin
created most of the quizzes for Popular Electronics. This is a listing
of all I have posted thus far.
