BASIC ELECTRICAL THEORY CHAPTER
1 FINAL EXAM QUESTIONS AND
CORRECT DETAILED ANSWERS
m Because of their light weight, ____ actively participate in the transfer of energy - Electrons
Electrostatic charge is due to an excess of, or a deficiency of, electrons between objects that have
separated.
True or False - True
Providing a path to the earth often helps reduce electrostatic charge
True or False - True
The discharge of electrons from a negatively charged object is sometimes seen as an arc, and the arc
distance is a function of the ______ between bodies - Static voltage and dielectric
Lightening frequently terminates to an elevated point and it strikes nonmetallic as well as metallic
objects with the same frequency
True or False - True
The termination of the lightening strike is unlikely to ignite combustible materials
True or False - False
Lightning protection is intended to protect the building itself, as well as the electrical equipment on or
inside the structure
True or False - False
Conductive materials have 1, 2, or 3 valence electrons. Elements with once valence electron, such as
silver, gold, and copper make the best conductors
True or False - True
Compounds can change the electrical characteristics of an individual atom. For example, the insulating
aluminum-oxide compound is very difficult to break and it often results in the overheating of aluminum
conductors at their terminals.
True or False - True
The end of the compass needle that points north is actually the south pole of the compass needle
seeking the earth's magnetic north pole.
True or False - True
