Question
How many electrons make up a charge of 20μC
Options
A.1.25 × 1014
B.2.23 × 1014
C.3.25 × 1014
D.5.25 × 1014
Solution
Change on an electron = 1.6 × 10-19 coulomb
No, of electrons required =
× 10-13 = 1.25 × 1014
No, of electrons required =
× 10-13 = 1.25 × 1014 Create a free account to view solution
