Answer:

n=1.18 x 10¹⁹

Explanation:

Given that

Current in the wire ,I = 1.9 A

The charge =q = n e

We know that

[tex]I=\dfrac{q}{t}[/tex]

I=Current

q=Charge

t=time

[tex]t=\dfrac{q}{I}[/tex]

Now by putting the values in the above equation we get'

q= 1.9 x 1 C

q= 1.9 C

q= n e

[tex]n=\dfrac{1.9}{1.602\times 10^{-19}}[/tex]

n=1.18 x 10¹⁹
