Tai va, noriu susizinoti kokio reikes prasyti parduotuveje... o tai kas bus jei ateisiu vos ka zinodamas, sakys neziniukas-loxas - eik lauk

  Nesakys (GAL?). Na jie taip pat nežinos ką tau pasiūlyti, juk jie nežino tavo schemos. Užeik pvz į www.rcl.lt ten gi rezistoriai pagal galią surūšiuoti. O tas puslapis kur tau generuoja tik siūlo, kad tau reikėtų naudoti rezistorių tiek ir tiek omų ir rekomenduoja minimalią galią atsižvelgiant į parametrus tavo atveju siūlo 0,25W

sita vakar kaip tik varciau, bet neradau (o gal tiesiog nepastebejau) reikiamos informacijos. Tu apie spalvotu ziedeliu zymejima?

Aš apie galingumą, o spalvoti žiedeliai tai varža nusako

Power dissipation

The power dissipated by a resistor is the voltage across the resistor multiplied by the current through the resistor:

    P = I^2 R = I V = \frac{V^2}{R}

All three equations are equivalent. The first is derived from Joule's law, and Ohm’s Law derives the other two from that.

The total amount of heat energy released is the integral of the power over time:

    W = \int_{t_1}^{t_2} v(t) i(t)\, dt.

If the average power dissipated is more than the resistor can safely dissipate, the resistor may depart from its nominal resistance, and may be damaged by overheating. Excessive power dissipation may raise the temperature of the resistor to a point where it burns out, which could cause a fire in adjacent components and materials.

Note that the nominal power rating of a resistor is not the same as the power that it can safely dissipate in practical use. Air circulation and proximity to a circuit board, ambient temperature, and other factors can reduce acceptable dissipation very significantly. Rated power dissipation may be given for an ambient temperature of 25°C in free air. Inside an equipment case at 60°C, rated dissipation will be significantly less; if we are dissipating a bit less than the maximum figure given by the manufacturer we may still be outside the safe operating area, and courting premature failure.
