June 1962 Popular Electronics

June 1962 Popular Electronics Cover - RF CafeTable of Contents

Wax nostalgic about and learn from the history of early electronics. See articles from Popular Electronics, published October 1954 - April 1985. All copyrights are hereby acknowledged.

Here is a quick, 10-question "Coil Function Quiz" about common coil (inductors) applications, common at least in 1962 when it appeared in the June issue of Popular Electronics magazine. Don't be scared off by the vacuum tubes that appear in three drawings. Just pretend they are transistors - it won't affect your answers. One of the coil applications is almost obsolete for most people as the nature of computer monitors and TV screens has changed significantly in the last decade, so CRTs are rarely seen. If you are one of the dwindling numbers of people who own and maintain vintage equipment, this probably will not present much of a challenge.

Coil Function Quiz, June 1962 Popular Electronics - RF Cafe

By Robert P. Balin

Coils used in electronic circuits often acquire special names which roughly describe their chief function. See if you can match coil drawings A - J with the "names" below.

See answers below.

Quizzes from vintage electronics magazines such as Popular Electronics, Electronics-World, QST, Radio-Electronics, 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.

About RF Cafe

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 World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
