  3. $6.5\times{10}^{19}$

  4. $6.25\times{10}^{15}$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

1 ampere means 1 coulomb of charge flows per second. Since each electron carries 1.6 × 10^-19 C, the number of electrons needed is 1 ÷ (1.6 × 10^-19) = 6.25 × 10^18. Option A correctly shows this calculation.
