Question:
I have a quetion about electrical current. Which kills,
voltage or amperage? My friends father says that it is possible to have a
very high voltage if the amperage is low,and that is how stun guns are
made. Is this true and could you possibly explain the principles to
me?
Replies:
Amperage. The amount of current determines the effect; the voltage and
the resistance of the path through the body determine the current.
Currents much below 100 mA are uncomfortable, but not life threatening;
currents around 100 mA can cause fibrillation, a chaotic, unproductive
heart rhythm that persists after the current is removed and is fatal
unless very prompt treatment is given; currents much above 100 mA can
lock up the heart without causing fibrillation and cause serious
burns.
