No, res povej! Zakaj ne piše npr POZOR, VELIKA JAKOST 16 A (amperov)?
Ker ni velike jakosti, je pa visoka napetost in jakost toka, če šlataš visoko napetost, je odvisna od tvoje upornosti.
Strange as it may seem, most fatal electric shocks happen to people who should know better. Here are some electro-medical facts that should make you think twice before taking that last chance.
It's The Current That Kills
Offhand it would seem that a shock of 10,000 volts would be more deadly than 100 volts. But this is not so! Individuals have been electrocuted by appliances using ordinary house currents of 110 volts and by electrical apparatus in industry using as little as 42 volts direct current. The real measure of shock's intensity lies in the amount of current (amperes) forced though the body, and not the voltage. Any electrical device used on a house wiring circuit can, under certain conditions, transmit a fatal current.
While any amount of current over 10 milliamps (0.01 amp) is capable of producing painful to severe shock, currents between 100 and 200 mA (0.1 to 0.2 amp) are lethal. Currents above 200 milliamps (0.2 amp), while producing severe burns and unconsciousness, do not usually cause death if the victim is given immediate attention. Resuscitation, consisting of artificial respiration, will usually revive the victim.
t is common knowledge that victims of high-voltage shock usually respond to artificial respiration more readily that the victims of low-voltage shock. The reason may be the merciful clamping of the heart, owing to the high current densities associated with high voltages. However, lest these details be misinterpreted, the only reasonable conclusion that can be drawn is that 75 volts are just as lethal as 750 volts.
The actual resistance of the body varies depending upon the points of contact and the skin condition (moist or dry). Between the ears, for example, the internal resistance (less the skin resistance) is only 100 ohms, while from hand to foot is closer to 500 ohms. The skin resistance may vary from 1000 ohms for wet skin to over 500,000 ohms for dry skin. Interestingly, while most people think of electricity in terms of voltage, the most dangerous aspect of electrical shock is the amperage, not the voltage.

Voltage vs. Amperage
Voltage and amperage are two measures of electrical current or flow of electrons. Voltage is a measure of the pressure that allows electrons to flow, while amperage is a measure of the volume of electrons. An electrical current at 1,000 volts is no more deadly than a current at 100 volts, but tiny changes in amperage can mean the difference between life and death when a person receives an electrical shock.
Although the physics are complicated, some experts use an analogy of a flowing river to explain the principles of electricity. In this analogy, voltage is equated with the steepness, or pitch of the river, while amperage is equated with the volume of water in the river. An electrical current with high voltage but very low amperage can be seen as a very narrow, small river flowing nearly vertical, like a tiny trickle of a waterfall. It would have little potential to really hurt you. But a large river with lots of water (amperage) can drown you even if the speed of flow (voltage) is relatively slow.
Of the two, amperage is what really creates the risk of death, which becomes clear when you understand just how little amperage is necessary to kill.

Do sedaj sem mislil, da je ravno obratno: čimbolj je tvoje telo prevodno (npr. znojna koža, mokra oblačila, mokra tla, ipd), tem večja je nevarnost.Če bi bil super prevoden sploh ne bi bilo težav z jakostjo toka, tekel bi skozi telo in še vedel nebi zato.
No, resno: je to prava analogija ali ni?vojko wrote:
Pa ja. Drava teče (dotok) v akumulacijsko jezero (prva vezna posoda); ko odpremo zapornice, Drava odteka (iztok) v nižjo strugo (druga vezna posoda). Če sta toka usklajena, se nivo ne spreminja ...
Aja, še dobro da nisi sanjal o nočnih posodah, ker bi se lahko še v mokroti zbudil.
Moja zgodba????!!! To je le reinterpretacija zgodbe iz Zbirke zgodbic, bargo! Ta pa je res bizarna ad nauseam!vojko wrote:

Predstavljaj si, da ti v oporoki napišeš, da se morajo tvoji prijatelji vsako soboto zbrati pri šanku, kjer običajno pijete, in jesti preste in piti vino, pri tem pa morajo biti prepričani, da jedo tvoje meso in pijejo tvojo kri, ko se te spominjajo! Halo!!!!!! Kaj bi si mislili o tvojem duševnem zdravju?
Ta tvoja zgodba je resnično bizarna zgodba.
Fil rouge???Ne vem, če je to ustrezna interpretacija. Dejstvo je, da si zrastel in to predvsem samo zato, ker si jedel in pil, če odmisliva potencial rasti, kaj ne? Sedaj si velik in močan, na vrhu piramide, kot praviš sam, in to ne zaradi mase, kot pa je slon težji od tebe, temveč zaradi besede, kaj ne?

Ni še bilo testa, objektivnega testa, ta še pride.
Prekleto, jaz sem pa mislil, da sem z elektriko končal...
No vidiš, spet napačno predvidevaš. Ali ni tako, da si brez elektrike mrtev?
