Back in the 1960s, Robert Balin created many quizzes on various electronics topics
for Popular Electronics magazine. I have already posted a couple dozen of them.
Here is the latest one on the subject of Units of Measure commonly found in electronics
work. I missed the one for the tape deck, but then I don't ever remember concerning myself
with the electrical and magnetic characteristics of tape decks.
Electronic Unit Quiz
By Robert P. Balin
Electronic devices have their sensitivity and operating ratings given in units that
describe their most important characteristics. See if you can match the 9 electronic
units listed below with the sketches (A through I).
1 Ohms per volt ___
2 Inches per second ___
3 Micromicrofarads per foot ___
4 Microvolts per meter
5 Cycles per second ___
6 Gilberts per centimeter
7 Volts per inch ___
8 Revolutions per minute
9 Volts per mil ___
See answers below.
Popular Electronics published many quizzes over the years
- some really simple and others not so simple. Robert Balin created many of the quizzes.

Electronic Unit Quiz Answers
1 - (G) The deflection sensitivity of a basic meter movement is given in ohms per
volt, which is the reciprocal of the current required to produce full scale deflection
of the meter.
2 - (I) The speed at which the tape passes the recording and playback heads in a tape
recorder is usually 7 1/2 or 3 3/4 inches per seconds (ips).
3 - (F) The conductor and metallic braid of a shielded cable form a capacitor, with
the insulating material between them acting as the dielectric. When the µµf.
per foot and the length of a cable are known, its total capacitive effect can be determined.
4 - (E) The strength of a received signal is measured in microvolts per meter - the
dielectric stress existing between two points in the wave front 1 meter apart and lying
on a line parallel to the electric lines of force.
5 - (H) The precise and stable frequency of vibration of a tuning fork given in cycles
per second is often used as a reference frequency in electronic testing.
6 - (B) The amount of magnetizing force required to produce a magnet of a given strength
is measured in gilberts, or ampere turns, per centimeter length of the magnetic circuit.
One gilbert per centimeter is called an "oersted."
7 - (A) The deflection sensitivity of an oscilloscope is specified by giving the amount
of input voltage required to produce a one inch peak-to-peak deflection on the cathode-ray
8 - (C) Phonograph turntable speeds used today are 16 2/3, 33 1/3, 45, and 78 revolutions
9 - (D) The insulating ability of tape is given as the number of volts it can withstand
per mil, or one-thousandth of an inch, of its thickness.

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 Internet was still largely an unknown entity at the time and not much was available
in the form of WYSIWYG
