Ch.1 Electrical Fundamentals: Final Exam Questions With
Correct Answers A+ Graded 2026-2027
Because of their light weight, _________ actively participate in the transfer of energy. -
CORRECT ANSWER -Electrons
Electrostatic charge is due to an excess of, or a deficiency of, electrons between objects that
have been separated. - CORRECT ANSWER -True
Providing a path to the earth often helps reduce electrostatic charge. - CORRECT 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 the bodies. - CORRECT ANSWER -static
voltage and dielectric
Lightning frequently terminates to an elevated point and it strikes nonmetallic as well as
metallic objects with the same frequency. - CORRECT ANSWER -True
The termination of the lighting stroke is unlikely to ignite combustible materials. - CORRECT
ANSWER -False, it is likely to ignite combustible materials.
Lighting protection is intended to protect the building itself, as well as the electrical equipment
on or inside the structure. - CORRECT ANSWER -False, only intended to protect the building
itself.
Conductive materials have one, two, or three valence electrons. Elements with one valence
electron, such as silver, copper, and gold make the best electrical conductors. - CORRECT
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 its presence often results in
the overheating of aluminum conductors at their terminals. - CORRECT ANSWER -True
