ATT Comp Test (FC) Exam || 2026 (Actual Exam) Questions with verified
Answers (Latest Update 2026) UPDATE!!
What is electrical Shock? - (ANSWER)A sensation and muscular spasm when electric current passes
through the body.
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
