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.
