The picture tube in a particular television draws a current of 16 A

How many electrons strike the viewing screen every second? (In electrons/s)

Respuesta :

The number of electrons per second is [tex]1\cdot 10^{20}[/tex]

Explanation:

The current intensity is defined as the amount of electric charge that passes through a given point in a certain time:

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

where

I is the current

q is the amount of charge

t is the time elapsed

Moreover, assuming that the charge carriers are electrons, the charge can be written as

[tex]q=Ne[/tex]

where

N is the number of electrons

[tex]e=1.6\cdot 10^{-19}C[/tex] is the charge of one electron

Re-writing the equation,

[tex]I=\frac{Ne}{t}[/tex]

Here we have:

I = 16 A

t = 1 s

Therefore, the number of electrons is

[tex]N=\frac{It}{e}=\frac{(16)(1)}{1.6\cdot 10^{-19}}=1\cdot 10^{20}[/tex]

The number of electrons (n) that strike the viewing screen every second is 10,000,000,000‬ electrons/s.

Given the following data:

  • Current = 16 Amperes.
  • Time = 1 seconds.

Scientific data:

Charge of electron = [tex]1.6 \times 10^{-19}\;C[/tex]

To calculate the number of electrons (N) that strike the viewing screen every second:

How to calculate number of electrons.

Mathematically, the quantity of charge per unit time is given by this formula:

[tex]Q =It=Ne\\\\N = \frac{It}{e}[/tex]

Where:

  • N is the number of electrons.
  • t is the time measured in seconds.
  • I is the current.
  • e is the charge of electrons.

Substituting the parameters into the formula, we have;

[tex]N = \frac{16 \times 1}{1.6 \times 10^{-19}}[/tex]

N = 10,000,000,000‬ electrons/s.
