It is common in electronics courses
for an analogy to be drawn between electrical and mechanical phenomena. In fact, a lot
of circuit analysis methods and equations apply directly to mechanics, and vice versa.
An LC (inductor-capacitor) oscillating tank circuit is akin to a spring and dashpot.
Resistance of a wire is likened to skin friction of water flowing through a hose. Who
among us can forget those lessons? This Electronic Analogy Quiz from the November 1961
edition of Popular Electronics presents a challenge both because some not-so-familiar
examples of analogies are offered, and because some are a real stretch. Therefore, don't
feel too bad if you don't get a few. That's my way of saying that I didn't get all of
them right ;-) Answers and explanations are at the bottom of the page.
Electronic Analogy Quiz
Electronic circuits perform functions similar to many mechanical devices and natural
phenomena, and finding an analogy between them often leads to a better understanding
of both. See if you can match the numbered electronic circuits on the left with the lettered
sketches on the right.
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.
