Robert Balin created this
Electronic Factor Quiz for the November 1966 edition of Popular Electronics
magazine. Your challenge is to match the drawing of a particular electronics circuit
or implement with the corresponding "factor." Examples are "current amplification factor,"
"damping factor," "modulation factor," "duty factor," "form factor," "quality factor,"
etc. There are ten in all. Of course on a quiz like this you cannot get just one answer wrong
- or any odd number for that matter. I managed to reverse #5 and #10 (I and B, respectively).
For some reason I couldn't remember what "form factor" was, but was sure that #10 was
a scale factor of sorts... wrong - a clear case of cranial rectumitis.
Electronic Factor Quiz
By Robert P. Balin
Most electronic technicians are familiar with such common expressions as "safety factor"
and "conversion factor." But how many are sure of the meaning of terms like "power factor"
and "duty factor"? See if you can associate: the electronic factor expressions
below (1-10) with the sketches (A-J) that suggest their application or meaning.
1) Current amplification factor
2) Damping factor
3) Modulation factor
4) Duty factor
5) Form factor
6) Quality factor.
7) Ripple factor
8) Velocity factor
9) Voltage amplification factor
10) Scale factor
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

Factor Quiz Answers
1 - C) The Current Amplification Factor, or d.c. beta, of a transistor common
emitter circuit is the ratio of the collector current (Ic) to base current
(Ib). Thus, β = Ic/Ib.
2 - G) The Damping Factor of an amplifier is the ratio of its output voltage
under normal load conditions to the measured change in the output voltage when the load
3 - J) The Modulation Factor of an AM waveform is the ratio of the maximum excursion
of the modulation envelope to the level of the un-modulated carrier. (Percent modulation
is obtained by multiplying the modulation factor by 100.)
4 - E) The Duty Factor of a pulse is the ratio of its "on" time to the total
duration of its "on-off" cycle.
5 - I) The Form Factor of a waveform is the ratio of its effective or r.m.s.
value to its average value.
6 - D) The Quality Factor, or simply Q, of a series-resonant circuit is the
ratio of either its inductive or capacitive reactance (XL or XC)
at resonance to its d.c. resistance.
7 - A) The Ripple Factor of a filtered power supply is the ratio of the r.m.s.
value of the a.c. components to the average value of its d.c. output voltage.
8 - H) The Velocity Factor of a transmission line is the ratio of the velocity
of the r.f. energy along the line to the velocity of the same energy traveling in free
9 - F) The Voltage Amplification Factor or mu (μ) of a vacuum-tube amplifier
is the ratio of the amplitude of the output signal appearing at its plate to the amplitude
of the input signal applied to its grid.
10 - B) The Scale Factor of a high-voltage probe is the constant by which the
meter reading must be multiplied to obtain the actual value of the voltage measured with
