Question

If a current of 5 Amperes flows through the conductor. The number of electrons flows per second will be

Answer 1

Given:

Current flowing through the conductor ($I$) = $5$ Ampere

Time ($t$) = $1$ second

To find:

The number of electrons flows per second ($N$)

Formula used:

$q\;=\;lt$

$q\;=\;Ne$

Where

$q$ is the total charge

$I$ is the current flown through the circuit

$t$ is the time

$N$ is the number of electrons

$e$ is the charge of an electron

Step-by-step Explanation:

The total charge that flows in $1$ second is given by

$q\;=\;lt$

$q\;=\;5\;\times\;1$

$q\;=\;5C$

The charge of an electron is given by $e\;=\;1.6\;\times\;10^{-19}\;C$

$q\;=\;Ne$

$N\;=\;\frac qe$

$N\;=\;\frac5{1.6\;\times\;10^{-19}}$

$N\;=\;3.125\;\times\;10^{19}$

Answer:

The number of electrons that flows per second is $N\;=\;3.125\;\times\;10^{19}$
