ACTUAL QUESTIONS AND CORRECT
ANSWERS
A closed circuit is an unbroken loop of conductive material that allows electrons to flow though
continuously without beginning or end - CORRECT ANSWER True
Current in a series circuit is different in different locations - CORRECT ANSWER True
Conventional current flow is where a surplus of electrons flow from negative to positive - CORRECT
ANSWER False
Static sensitive devices can be damaged by as little as 3000 volts - CORRECT ANSWER False
(10v)
Neutrons or proteins can be dislodged from atoms much easier than electrons. - CORRECT ANSWER
False (Electrons can be, outer)
If a circuit containing a voltage source is broken, the full voltage or that source will appear across the
points of the break. - CORRECT ANSWER True
For electrons to flow continuously (indefinitely) through a conductor, there must be a complete,
unbroken path for them to move both into and out that conductor. - CORRECT ANSWER True
Free electrons are called valance electrons - CORRECT ANSWER True
Electrons can be motivated to flow through a conductor by the same force manifested in static
electricity. - CORRECT ANSWER True
Dynamic electricity, or electric current, is the uniform motion of electrons through a conductor -
CORRECT ANSWER True
, If a circuit is "broken, or open" that means its conductive elements do not form a complete path, and
continuous electrons flow cannot occur in it - CORRECT ANSWER True
The terms open and closed refer to switches as well as entire circuits. An open switch is one without
continuity: electrons cannot flow though it. A closed switch is one that provides a direct (low
resistance) path for electrons to flow through it. - CORRECT ANSWER True
Voltage is the measure of a specific potential energy(potential energy per unit charge) between two
locations. In Layman's terms, it is the measure of "push" available to motivate electrons. - CORRECT
ANSWER True
A short circuit is one where the continuity has been broken by an interruption in the path for electrons
to flow. - CORRECT ANSWER False
The locations of a break in a circuit is irrelevant to its inability to sustain continuous electron flow.
Any break, anywhere in a circuit prevent electron flow throughout the circuit. - CORRECT ANSWER
True
Static electricity is an unmoving (if on an insulator), accumulated charge formed by either an excess
or deficiency of electrons on an object. - CORRECT ANSWER True
When a voltage source is connected to a closed circuit, the voltage will cause a uniform flow of
electrons through that circuit called a current. - CORRECT ANSWER True
The number of electrons in an atoms orbit determines its identity as a unique element - CORRECT
ANSWER False (protons)
All metals are electrically conductive - CORRECT ANSWER true
a device designed to open or close a circuit under controlled conditions is called a switch - CORRECT
ANSWER true
In insulator materials, the electrons are not free to move - CORRECT ANSWER true
