ATT TEST 3 EXAM STUDY GUIDE 2026
COMPLETE QUESTIONS AND ANSWERS
● What is a GFCI? Answer: Ground Fault Circuit Interrupter
(automatically shut's off electrical flow in the event of an overload)
● TS Transformers Answer: Open: 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 Answer: Potential of electric energy; pressure of
electrons pushing away from each other.
● Current is defined as __________________________. Answer: a flow
of electric charge
● What are some factors affecting shock? Answer: Amount 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? Answer:
The general health of the victim.
, ● Ways to prevent shock? Answer: Isolate, insulate & ground
● What is the minimum AC current required to cause severe muscle
contractions? Answer: 12 mA
● How much more DC is required to freeze the body than AC? Answer:
5 times more
● What types of burns are there? Answer: Electrical burns, arc burns,
and thermal contact burns
● Electrical burns are what? Answer: Electrical current flowing through
tissue or bones
● Arc burns are what? Answer: Electrical current flowing through tissue
or bones
● Thermal contact burns are what? Answer: When skin comes in contact
with hot surfaces of overheated electrical conductors
● Factors of electrical accidents Answer: Unsafe equipment, unsafe
environment, and unsafe work practices
