Question

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)

Answer 1

Answer:

The $6.25 \times 10^{23}$ electrons are moving through the superconductor per second.

Explanation:

Given :

Current $I = 1 \times 10^{5}$ A

Charge of electron $e = 1.6 \times 10^{-19}$ C

Time $t = 1$ sec

From the formula of current,

Current is the number of charges flowing per unit time.

   $I = \frac{ne}{t}$

Where $n =$ number of charges means in our case number of electrons

   $n = \frac{It}{e}$

   $n = \frac{1 \times 10^{5} }{1.6 \times 10^{-19} }$

   $n = 6.25 \times 10^{23}$

Therefore, $6.25 \times 10^{23}$ electrons are moving through the superconductor per second.
