Questions and Answers
Electrical Shock - -when electrical current passes through the body
- Electrical Current - -movement or flow of electrons
- Severity of electrical shock depends on: - -Amount of current
Path of current
Amount of time
- High voltage is typically - -115VAC or more
- Electrical Burns - -Burns caused by electrical current flowing through the
body tissues and bones.
- Arc Burns - -Caused by electrical energy traveling from an area of high
resistance to an area of low resistance.
- An arc burn on the skin is also known as - -Flash burn
- Three types of burns - -Arc Burn , Electrical Burn, Thermal Burn

, - Element - -One of more than 100 known substances that cannot be
divided into simpler substances by chemical means
- Molecule - -Smallest particle into which a substance can theoretically be
divided and maintain its chemical properties.

- Mixtures - -Two or more molecules or elements are grouped together, and
each molecule maintains chemical identity.
- Protons - -positively charged particles inside the nucleus
- Neutron - -a neutral particle in the nucleus of an atom

- Negative Ion - -Atom that has more than its normal number of electrons
- Positive Ion - -Atom with less than its normal number of electrons
- Law of Electrostatics - -Law that states like charges repel and unlike
charges attract.
