Question

1 ampere current is arriving in a conducting wire . What is the number of electrons per second through a point of it ? (e=1.6×10^-19c)

Answer 1

Answer:

$6.25 \: \times \: {10}^{18} \: electrons$ = 625 x 10^16 electrons

Explanation:

$current \: = \: \frac{total \: charge}{total \: time} \\ = > current \: = \frac{no. \: of \: electrons \: \times \: charge \: of \:one \: electron }{time} \\ = > \:1 \: = \: \frac{no. \: of \: electrons \: \times \: 1.6 \: \times \: {10}^{ - 19} }{1} \\ = > no. \: of \: electrons \: flowing \: through \: a \: point \: in \: one \: second = \frac{1}{1.6 \: \times \: {10}^{ - 19} } \\ = 6.25 \: \times \: {10}^{18 } \: electrons \:$
