ATT COMP TEST (FC)EXAM
QUESTIONS AND ANSWERS
, What is electrical Shock? - ANSWERSA sensation and muscular spasm when electric
current passes through the body.
What is a GFCI? - ANSWERSGround Fault Circuit Interrupter (automatically shut's off
electrical flow in the event of an overload)
TS Transformers - ANSWERSOpen: T doesn't generate output V
Short: could be partial which would then change number of coils so Ep would change or
Es
What is voltage - ANSWERSPotential of electric energy; pressure of electrons pushing
away from each other.
Current is defined as __________________________. - ANSWERSa flow of electric
charge
What are some factors affecting shock? - ANSWERSAmount of current, path of current,
amount of body resistance, and length of time current flows in body
What is not a primary factor in severity of an electric shock? - ANSWERSThe general
health of the victim.
Ways to prevent shock? - ANSWERSIsolate, insulate & ground
What is the minimum AC current required to cause severe muscle contractions? -
ANSWERS12 mA
How much more DC is required to freeze the body than AC? - ANSWERS5 times more
What types of burns are there? - ANSWERSElectrical burns, arc burns, and thermal
contact burns
Electrical burns are what? - ANSWERSElectrical current flowing through tissue or
bones
Arc burns are what? - ANSWERSElectrical current flowing through tissue or bones
Thermal contact burns are what? - ANSWERSWhen skin comes in contact with hot
surfaces of overheated electrical conductors
Factors of electrical accidents - ANSWERSUnsafe equipment, unsafe environment, and
unsafe work practices
