Basic Electrical Theory Chapter 1 Final
Exam Questions With Correct Answers
Because of their light weight, ____ actively participate in the transfer of energy -
answer✔Electrons
Electrostatic charge is due to an excess of, or a deficiency of, electrons between objects that have
separated.
True or False - answer✔True
Providing a path to the earth often helps reduce electrostatic charge
True or False - answer✔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 - answer✔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 - answer✔True
The termination of the lightening strike is unlikely to ignite combustible materials
True or False - answer✔False
Lightning protection is intended to protect the building itself, as well as the electrical equipment
on or inside the structure
True or False - answer✔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 - answer✔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.
