Safety With Electricity

-- current is dangerous, not voltage

-- DC currents seize up your muscles upon contact

-- do not touch someone on a DC current, as you will seize up too

-- AC will cause you to seize up and then release it and be freed from the current

-- most products say if the current is AC or DC

-- 1/10 of an amp directly across your heart will kill you

-- touching a charge of more than 1/10 of an amp may not kill you, as the skin is resistive and won’t carry much electrical charge

-- electrons flow easily in water, which is why mixing electronics and water is bad

Electricity Vocabulary

Electrostatic = electricity at rest

Conduction = when objects are in direct contact with each other, electrons move from one to the other

Friction = rubbing two surfaces, and electrons move from one surface to another

Ohms = units for electrical resistance

Amperes = units for current

Conductor = a material that allows electrical current to pass

Insulator = a material that doesn’t allow electrical current to pass
