robot incarcare baterii


Recommended Posts

buna ziua . la acest robot este dus transformatorul care a fost bobinat cu sarma de aluminiu emailat , intrebare este daca al bobinez cu sarma de cupru trebuie respectat diametrul sarmei ca sa aiba acelasi randament , stiind ca sarma de cupru are rezistenta diferita de cea de aluminiu . multumesc
