How many electron flow through a light bulb each second if the current flow through the light bulb 0.75A.The electric charge of one electron is 1.6 x 10-19C

Respuesta :

Answer:

[tex]n=4.68\times 10^{18}[/tex]

Explanation:

The current through the bulb, I = 0.75 A

We need to find the number of electrons flowing per second. We know that the electric current is given by :

[tex]I=\dfrac{ne}{t}\\\\n=\dfrac{It}{e}\\\\n=\dfrac{0.75\times 1}{1.6\times 10^{-19}}\\\\n=4.68\times 10^{18}[/tex]

So, there are [tex]4.68\times 10^{18}[/tex] electrons flowing per second.

There are "[tex]4.68\times 10^{18}[/tex]" electron flowing per second.

Electric charge:

Whenever retained inside an electric as well as the magnetic field, this same basic physical attribute of matter which thus permits it to perceive a force, is considered as Electric charge.

According to the question,

Current flow, I = 0.75 A

Electric charge of one electron, e = 1.6 x 10⁻¹⁹ C

As we know the relation,

Current, I = [tex]\frac{ne}{t}[/tex]

or,

→ n = [tex]\frac{It}{e}[/tex]

By substituting the given values in the above formula, we get

      = [tex]\frac{0.75\times 1}{1.6\times 10^{-19}}[/tex]

      = [tex]4.68\times 10^{18}[/tex]

Thus the approach above is appropriate.
