Why electricity can be dangerous?

Answer 1

The "internet" inside your body: the network of nerves that carries commands

from your brain to your muscles, and carries sights, sounds, and feelings back

to your brain from everywhere else, is an electrical network. The messages

start out as small voltages, and they travel through the nerves as small currents.

Very simply, if a larger voltage comes along and causes a larger current to flow

through a nerve, it can drown out the signals that are supposed to be there.

Some possible results might be: Making your heart beat when it shouldn't, and

disrupting the sync pattern between different parts of the heart; blocking the

signal to your diaphragm telling it that it's time to breathe; sending a signal to

your arm muscle telling it to contract, but so loud and strong that the muscle

breaks your arm.

If the outside voltage is really high, and it pumps a really high current through

the nerves or other tissues, then it's easy to understand the damage in terms

of the everyday results of overloading a household circuit: wire gets hot and

burns its insulation, wire melts, fuse blows, circuit breaker trips, flesh burns,

brain-cables short-circuit, software gets corrupted, motors burn out etc.

Your cellphone is built to operate on electricity, and so is your body. But your

cellphone operates on a 3.4-volt battery, and would not like it if you plugged it

directly into a 110-volt outlet. Similarly, in the few hundred years that we've

been playing with electricity, our bodies have not evolved to play nicely with the

voltage and current levels that we use for our blow-driers and electric stoves.

Answer 2

it is VERY dangerous make sure u keep it away from water and dont play aroud electric pole and DONT play with wires . make sure u know what to do when you see something bad happening with electricity.

The question was "why electricity can be dangerous". That tangle does not answer it. Very simply, an electric shock can kill by stopping the heart, but even if not fatal, high currents can cause severe external and internal burns.
