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

Options

A. `10^(19)`
B. `2xx10^(19)`
C. `3xx10^(19)`
D. `7xx10^(20)`

Answer

C

Explanation

Let N electrons are flowing through a conductor in time t.
`therefore` Current, `I=(Ne)/(t)`
or `(N)/(t)=(I)/(e)=(4.8)/(1.6xx10^(-19))=3xx10^(19)` electrons per second
