Why do we get a shock from electricity?
Electricity shocks us, because it is an outside force that
interferes with the internal electricity our bodies'
nervous systems generate.
To fully understand why the chance encounter of these two
electrical forces results in a shock to our systems, we
must first understand the fundamentals of electricity
itself.
In scientific terms, electricity is considered a
fundamental force, one that is extremely basic, and has
been in existence since the beginning of time. Further
simplified, it is so basic, that it defies explanation, and
is Mother Nature's way of saying "Because I said so"!
Electricity comprises positive and negative charges,
opposite charges attract each other, and similar charges
repel each other. Those charges attracted to each other can
be separated, with the end product being potential energy,
that is, energy that will be released as voltage, should
the two reunite. We pay electric companies to separate the
positive and negative charges for us, so that we have
electrical energy at our disposal.
In order for the charges to reunite, and for the potential
energy to be released as voltage, a conductor, a channel
that they can flow through, is needed. Insulators, such as
paper and glass make poor conductors, while wire and water
make excellent conductors. Unfortunately, since the human
body consists primarily of water, it too provides a superb
conductor for electrical energy, or voltage.
