COMPLETE 100 QUESTIONS AND CORRECT
DETAILED ANSWERS (VERIFIED ANSWERS)
|ALREADY GRADED A+||BRAND NEW!!
Electrical Shock Sensation and muscular spasm cause when electric current
passes through the body
Voltage Potential of electric energy; pressure of electrons pushing away
from each other
Current Flow of electrons
Most dangerous paths Hand to hand & left hand to either foot
Amount of current, path of current, amount of body
Factors affecting shock
resistance, length of time current flows in body
3 ways to prevent shock Isolate, insulate & ground
Grounding conductor Used to form a low resistance path from the ground to the
metallic tool case
12MA Minimum AC current required to cause severe muscle
contractions
The body Acts like a conductor when it becomes part of a circuit
5xs How much more DC is required to freeze the body rather than AC
Burns Electrical burns, arc burns, thermal contact burns
Electrical burns Electrical current flowing through tissue or bones
Arc burns High temperatures near the body produced by electric arc or
explosion
Thermal contact burns When skin comes in contact with hot surfaces of overheated
electrical conductors
Electrical Arcs Where short circuit occurs; may cause fires
Extremely high arcs Damage equipment dispersing metal fragments
Low energy arcs Explode containing flammable gas, vapors, or combustible dusts
Factors of electrical accidents 1. Unsafe equipment 2. Unsafe environment 3.unsafe work
practices
Insulator Any material with high resistance to electrical current
American wire gauge size, max voltage,
Identify conductors and
cables
