Factors affecting shock - Correct Answer-Amount of current, path of current, amount of body resistance, length of time current flows in body
Ways to prevent shock (3) - Correct Answer-Isolate, insulate & ground
Minimum AC current required to cause severe muscle contractions - Correct Answer-12
mA
How much more DC is required to freeze the body rather than AC - Correct Answer-5 times more
