ATT COMP TEST EXAM QUESTIONS
WITH VERIFIED ANSWERS. A+ GRADE
2025/2026.
What is electrical Shock? - ANS A sensation and muscular spasm when electric current passes
through the body.
What is a GFCI? - ANS Ground Fault Circuit Interrupter (automatically shut's off electrical
flow in the event of an overload)
TS Transformers - ANS 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 - ANS Potential of electric energy; pressure of electrons pushing away from
each other.
Current is defined as __________________________. - ANS a flow of electric charge
What are some factors affecting shock? - ANS Amount of current, path of current, amount of
body resistance, and length of time current flows in body

Arc burns are what? - ANS Electrical current flowing through tissue or bones
Thermal contact burns are what? - ANS When skin comes in contact with hot surfaces of
overheated electrical conductors
Factors of electrical accidents - ANS Unsafe equipment, unsafe environment, and unsafe
work practices
