2. c) Mini-Voltmetru RED ,GREEN sau BLUE 0-100V - 15lei/buc

Afisaj 0.36"

 

Se da o sursa liniara , 0 - 15 V .

Voltmetrul de mai sus ( cu 3 fire ) poate fi utlizat pentru a afisa tensiunea la iesirea din sursa ( firul rosu ) daca il alimentez ( prin firul alb ) inainte de elementul serie ?

Adica , imi afiseaza si tensiunile in intervalul 0 - 3 V ?

[soringt]

da, afiseaza si in intervalul 0-3V. Dar este invers, firul rosu este cel de alim iar cel alb de masura.
