Na, visdar kaupiu informacija. Jau del ryskumo panasu jog bus arti reikiamu parametru.

Dabar del varzos. Pagal duota linka, kur parodo kaip jungti diodus, paraso varzos dydi (sakykim R=15ohms)

O apacioje
    *  each 15 ohm resistor dissipates 73.5 mW
    * the wizard thinks 1/4W resistors are fine for your application Help
    * together, all resistors dissipate 73.5 mW
    * together, the diodes dissipate 560 mW
    * total power dissipated by the array is 633.5 mW
    * the array draws current of 70 mA from the source.

Tai pagal kuriuos duomenis remtis, kokia varza pirkti?? Ar svarbus abu parametrai??
