Question

Sarcina electrica 1C este determinata de:
a) un electron in exces
b) 1.6 ori 10 la puterea -19 electroni
c) lipsa unui electron
d) lipsa a 625 ori 10 la puterea 16 electroni

Answer 1

$\displaystyle Sarcina \ electrica \ elementara \ in \ modul \ are \ valoarea : \\ \\ q=1,6*10^{-19} \\ \\ Nr \ de \ e^{-} \ aferenti \ este \ : \\ \\ N=\dfrac{1}{1,6*10^{-19}}=0,625*10^{19}=625*10^{16}e^- \\ \\ Raspuns \ corect \ d.$
