Some superconductors are capable of carrying a very large quantity of current. If the measured current is 1.00 ´ 105 A, how many electrons are moving through the superconductor per second? (e = 1.60 ´ 10-19 C)

Respuesta :

Answer:

The [tex]6.25 \times 10^{23}[/tex] electrons are moving through the superconductor per second.

Explanation:

Given :

Current [tex]I = 1 \times 10^{5}[/tex] A

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

Time [tex]t = 1[/tex] sec

From the formula of current,

Current is the number of charges flowing per unit time.

   [tex]I = \frac{ne}{t}[/tex]

Where [tex]n =[/tex] number of charges means in our case number of electrons

   [tex]n = \frac{It}{e}[/tex]

   [tex]n = \frac{1 \times 10^{5} }{1.6 \times 10^{-19} }[/tex]

   [tex]n = 6.25 \times 10^{23}[/tex]

Therefore, [tex]6.25 \times 10^{23}[/tex] electrons are moving through the superconductor per second.
