Electronic Analogy Quiz Answers
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.

This electronics analogy quiz is a little easier than a few of the others published in Popular Electronics because all of the electrical and mechanical objects depicted here are very familiar. The concepts might seem trivial to those of us who have been immersed in the science for decades, but I for one can remember when first hearing these analogies how helpful they were. Not only that, but I also recall during physics and mechanics courses in college being amazed at the similarity of equations shared by electrical and mechanical processes.
