Question

is 5 into 10 raise to the power 19 electrons flow through conductor in 4 seconds then the current is charge of electron is equals to 1.6 into 10 to the power minus 19 coulomb

Answer 1

charge on each electron=1.6×10^-19
number of electron =5×10^19
hence, total charge =1.6×10^-19×5×10^19
=8
time taken=4s
we know that ,
I=total q /time taken
I=8/4
I=2A
hence the current =2A
hope you have got your answer

Answer 2

Concept:

An electron is a subatomic particle of which the electric charge is negative one elementary charge.

Given:

Charge on an electron $=1.6\times 10^{-19}$

Number of electrons $=5\times 10^{19}$

The time taken by the electrons to flow through the conductor is $4sec$.

Find:

The current flows through the conductor.

Solution:

Charge on an electron $=1.6\times 10^{-19}$

Number of electrons $=5\times 10^{19}$

Time, $t=4sec$

So, the total charge:

$Q=1.6\times 10^{-19}\times5\times 10^{19}\\Q=8C$

Now we know,

$I=\frac{Q}{t}$

$I=\frac{8}{4} A$

$I=2A$

The current flowing through the conductor is $2A$.
