ANSWERS GRADED A+
●● 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
●● What should you do first if someone has been shocked?
