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).
Electronic Unit Quiz

9 Volts per mil
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 per minute.
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.
