    Nezd vissza, nem eloszor irom be, hogy vennek.

    Ezt talaltam most hirtelen a feszultsegemelessel kapcsolatban.
    "As voltage increases, temperature increases exponentially." Not really exponentially, but sort of. Simply from the standpoint of the generation of heat by the circuit, increasing the voltage by a certain fractional factor, say, x (like, 1.10, a 10% increase) will also increase the current that flows through the circuit by that same factor. This means that the heat generated (power dissipated) in that circuit, which is the product of voltage time current, increases by the square of x (in the example here, 1.1 squared, or 1.21 - thus 21% higher heat generation for a 10% voltage increase. But the effect gets magnified a bit because the rate of heat flow out of the circuit is limited by the thermal conductivity of the materials, so the temperature right at the circuit active elements on the chip rises even more than you might guess from that power increase. The results is not exactly an exponential relationship between voltage and temperature, but it is very significant.

    Ertelemszeruen ha csokken a feszultseg, csokken az aramfelvetel es a termelt ho is.

    Fogyasztasmero: szvsz erre a celre barmelyik megfelel. Conrad-ba bemesz pl es leemelsz egyet a polcrol. Ha nem is lesz teljes mertekben pontos, a kulonbozo beallitasok kozotti fogyasztaskulonbseget jol fogja mutatni.
