Robert Balin created
many quizzes for Popular Electronics magazine during the 1960s and
1970s. Topics included series circuits, electrochemistry, electronic analogy,
electronic coupling, electronics analogy, audio, electronic units, capacitor
circuits, AC circuit theory, magnetic phenomena, electronics geography,
electronic noise, plugs and jacks, electronic switching, diodes, and many more.
This "Electronics Physics Quiz" is the 59th that I have posted. It challenges
you to name the effects that were first noticed as the result of unexpected
actions during laboratory experiments. Many of the names, as you might expect,
eponymously honor their progenitors. My score was 80%.
Electronics Physics Quiz
By Robert P. Balin
The scientific principles behind today's electronic devices were discovered when
experimenters first observed certain strange occurrences. In time, these effects
were developed into practical components having many applications. For example,
the Doppler effect, an apparent shift in the frequency of the sound from a moving
source, is utilized in modern radar systems. To test your knowledge of physics,
see if you can match the following electronic effects (which are illustrated below)
to the names (A to J) also given below.
Answer Choices
A. Edison effect
B. Hall effect
C. Joule effect or magnetostriction
D. Miller effect
E. Peltier effect
F. Piezoelectric effect
G. Seebeck effect
H. Thomson effect
I. Volta effect or contact potential
J. Zener effect
(see correct answers at bottom of page)
1. When a nickel rod is magnetized, it becomes shorter in length.
2. When a bar of metal is heated at one end, a voltage is produced between the
hot and cold ends.
3. When a dc current is sent through a semiconductor pn junction, the junction
becomes hotter or cooler depending on the direction of the current.
4. When the junction of two dissimilar metal strips is heated, a voltage is produced
between the free ends
5. When the input signal to a vacuum tube is increased, the tube's input capacitance
is also increased, thereby reducing the frequency response of the stage.
6. When a Rochelle salt crystal is twisted, a voltage is produced between its
faces.
7. When two dissimilar metals are placed in close contact with each other, a
voltage is produced between the free ends.
8. When the plate in a vacuum tube is made positive with respect to the filament,
electrons flow through the vacuum from the filament to the plate.
9. When a current flows through a crystal of InAs held in a magnetic field, a
voltage is produced between the edges of the crystal which lie parallel to direction
of current.
10. When the reverse voltage applied to a crystal diode reaches a critical value,
the current increases very rapidly, indicating a sharp drop in reverse resistance.

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.
