Here is a different type
of quiz from Popular Electronics' master quiz-maker, Robert P. Balin. Rather
than the typical format where you need to match a word or another picture with a
picture, this one requires you to consider each description and decide whether it
best describes an inductive, capacitive, or reactive circuit. I confess to messing
up on question 20, because I couldn't remember whether a lagging power factor referred
to voltage lagging current or current lagging voltage. Hint: It refers to current
lagging voltage. Another hint: Remember the ELI the ICE man mnemonic.
Resistive? Inductive? or Capacitive? Quiz
By Robert P. Balin
In all of electricity and electronics, there are only three basic properties:
resistance, inductance, and capacitance. These properties, or combinations of them,
can give us complete control over current, voltage, phase, and power in any electric
circuit.
Since resistive, inductive, and capacitive circuits operate on entirely different
principles, each type of circuit has a distinctive character of its own. But regardless
of where or how these three basic properties are used, they retain their individual
characteristics. From the descriptions of their behavior given below, can you identify
the type of circuit referred to?
Fill in the blank with R if you think the circuit is resistive; L, if inductive;
and C, if capacitive.
1) Electrical energy can remain stored in this type of circuit even after
the source of energy is removed ___
2) The current in this type of circuit is always in phase with the source
of voltage ___
3) Arcing is likely to occur between the contacts when this circuit is
opened ___
4) Electrical energy is stored in the magnetic fields found in this type
of circuit ___
5) This circuit tries to keep its voltages constant ___
6) The flywheel effect is characteristic of this type of circuit
___
7) Electrostatic fields are used in this circuit ___
8) This type of circuit always has unity power factor ___
9) This circuit acts almost like a short circuit to a.c. voltages
___
10) Voltage across this circuit builds up to a high potential instantaneously
when the circuit is opened ___
11) If the frequency of the source voltage for this circuit is increased,
the current goes down ___
12) The current in this circuit leads the source voltage ___
13) This type of circuit can act almost like an open circuit at the instant
that power is applied ___
14) No electrical energy is stored in this type of circuit at any time
___
15) Because of the surge currents in this circuit, its fuse may blow when
power is applied ___
16) Conductor or component insulation may be damaged when power is removed
from this circuit ___
17) This type of circuit tries to keep its current constant ___
18) Current never actually flows through this type of circuit ___
19) In this circuit the current remains the same regardless of changes
in the frequency of the source voltage ___
20) This type of circuit has a lagging power 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
created most of the quizzes for Popular Electronics. This is a listing
of all I have posted thus far.
