Residential Wiring Exam Prep Questions with
Correct Verified Solutions
Ch. 1
Safety
Electrical Burn
A burn that occurs when electricity passes through the body
Arc Flash
An explosion that takes place when electricity short-circuits through the air or across inadequate
insulation
Personal Protective Equipment (PPE)
The clothing and equipment worn to provide protection from hazards
Insulated Tools
Tools, with a non-conductive covering that are designed to prevent the transfer of electricity
from the tool to the user
Lockout Device
A safety device that prevents the energizing of a circuit by locking switches, breakers, valves, or
enclosures
Tagout Device
The identification procedure that is used to let other workers know who applied a lockout
,Blockout Device
A safety device used to stop machinery from moving
Ch. 2
Electrical Energy Fundamentals
Atom
The Smallest part of an element
Protons
The positively charged particles of an atom
Neutrons
The particles with no charge in the nucleus of an atom
Electrons
Negatively charged particles that orbit the nucleus of the atom
Free Electrons
Electrons that are loosely bound to the nucleus of an atom and can easily leave to join other
atoms
Conductor
A substance that allows electrons to flow freely through it; an object having good conductivity
Insulators
Substances that prevent electrons from flowing freely
, Equilibrium
When two connected bodies have the same number of electrons; a balanced condition
Electrical Potential
The ability to provide electrons
Direct Current (DC)
A current that flows in one direction
Alternating Current (AC)
A periodic current that continuously reverses direction
Cycles
A cycle is one complete repetition of a wave-form or signal. The rate at which the signal repeats
itself is expressed in cycles per second, or Hertz Hz.
Hertz
A unit of frequency that equals one cycle per second. (Named after Heinrich Hertz)
1 Complete Cycle Equals
60 Turns Per Sec. And/Or 60 Hz.
Anode
The Positive terminal of a battery
Cathode
The negative terminal of a battery
