Electricity has long and long gone into our daily routine, which seems to have been opened during the invention of the wheel, perhaps even before. The popularity of the use of electricity is very simple: it is electricity that drives different machines and machines, electric vehicles and all possible domestic equipment.

It helps to facilitate various work and leisure activities: remember how much time we spend in front of TV, computer or home cinema. But electricity doesn't show, it doesn't make any noise, it doesn't have color and smell.

It can only be detected by devices, in the simplest case the device is a normal lamp or a tracer. But often this " invisibility " can turn electricity from a good assistant to an evil enemy, from creative energy to destructive and sometimes even fatal. Moreover, failures in electricity can cause fear for such work for life.

Domestic experience Electricity

Every one of us, of course, had to turn a light bulb, repair the burnt cord at the cliff, retract the contact in the rod. However, it is not necessary to have special electrotechnical education. Just as you don't need to know before the smallest detail, the internal combustion engine device to become an amateur. Minor failures can be rectified, not knowing the whole of the vehicle, but in serious cases it is always possible to contact the service.

Similarly, with electricity: it is absolutely not necessary to invite an electric mounter from the LPD to replace an inappropriate switch or dispenser. But there is a need to know how dangerous electricity is, and what rules must be respected so as not to lose a wish for such work forever. I mean, it's not fun to sit around all day and wait for a good uncle to come, and it's gonna squeeze the "killed" machine or PC because you're afraid to do it yourself or you just don't know it.

The danger of electricity

So why is electricity dangerous to humans? There are two main reasons. It is a simple mechanical damage to the tissue, and it also affects the human nervous system with very severe consequences.

From the history of electricity development, it is known that the Italian doctor, Luigi Galvani, used pre-paraged frogs in his experience, since no electrifier devices were available at that time. The weakness of the power flow through the nervous ends has forced the muscles of the frog-cloth.
