Current of 4.8 amperes is flowing through a conductor. The number of electrons per second will be

A

3×10193 \times 10 ^ { 19 }

B

7.68×10217.68 \times 10 ^ { 21 }

C

7.68×10207.68 \times 10 ^ { 20 }

D

3×10203 \times 10 ^ { 20 }

Answer

3×10193 \times 10 ^ { 19 }

Explanation

Solution

Number of electrons flowing per second

nt=ie\frac { n } { t } = \frac { i } { e } =4.8/1.6×10−19=3×1019= 4.8 / 1.6 \times 10 ^ { - 19 } = 3 \times 10 ^ { 19 }
