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.

Dear all, I just want to ask an expert on this forum for some insights. For the magnetic balance test, when applied voltage on a Delta-Star transformer e.g. Dyn11, the following relationships apply for HV side: 1. H1-H2 = H2-H3 H3-H1 2. H2-H3 = H3-H1 H1-H2 3. H3-H1 = H1-H2 H2-H3 For the LV side also: 4. X1-X0 = X2-X0 X3-X0 5. X2-X0 = X3-X0 X1-X0 6. X3-X0 = X1-X0 X2-X0 Is there a similar pattern for Y-d, Y-Y, D-d? And how about Y-z, D-z, Z-y transformers? I've tested a YNzn5 transformer and for LV side I don't see the pattern. In this particular case I got for LV side the following (see values below): H1-H0 H2-H0 H3-H0 X0-X1 X0-X2 X0-X3 128.0 119.9 7.2 29.2 13.3 15.8 70.7 128.4 59.2 23.4 22.0 3.6 7.2 120.1 128.1 13.4 29.3 15.8 What is the relationship here for LV? For row 1 I see the relationship, for row 3 I also see but it's shifted, but for row 2 I don't see such relationship. Any suggestions, answers, someone?
