If 1 A current flows in a circuit, the number of electrons flowing through this circuit is
Correct answer: A. 0.625 x 10^19
- A. 0.625 x 10^19
- B. 1.6 x 10^19
- C. 1.6 x 10^-19
- D. 0.625 x 10^-19
Explanation
Since 1 ampere equals 1 coulomb per second and one electron carries approximately 1.6 × 10^-19 C, the number of electrons per second is 1/(1.6 × 10^-19) = 0.625 × 10^19. Thus option a gives the electron flow rate implied by 1 A.
