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
,age 2 of 19

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
