Wax nostalgic about and learn from the history of early electronics. See articles
from Popular Electronics,

Here is another electronics
quiz for you to try. It covers the functions of resistors in various circuits. The
quiz appeared in the January 1962 edition of Popular Electronics, compliments of
Robert P. Balin. I got 100%, just
for the record - PhD not required, by the way. Having worked with tubes in the
days of yore helps with figure B since it does not really
have a direct transistor equivalent, but by process of elimination you can get it.
Resistor Function Quiz
By Robert P. Balin
Resistors find more uses in electronic equipment than any other component. See
if you can match the functions of the resistors listed at right with the letters
(A through I) representing their applications in the diagrams at left.
1 Current limiting resistor ___
2 Damping resistor ___
3 Ballast resistor ___
4 Filter resistor ___
5 Self-bias resistor ___
6 Isolation resistor ___
7 Range resistor ___
8 Parasitic suppressor ___
9 Bleeder resistor ___
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.
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 typing up your telephone line, and a nice lady's voice announced "You've Got
Mail" when a new message arrived...
