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

The
`6.25 * 10^(23)` electrons are moving through the superconductor per second.

Step-by-step explanation:

Given :

Current
`I = 1 * 10^(5)` A

Charge of electron
`e = 1.6 * 10^(-19)` C

Time
`t = 1` sec

From the formula of current,

Current is the number of charges flowing per unit time.

`I = (ne)/(t)`

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

`n = (It)/(e)`

`n = (1 * 10^(5) )/(1.6 * 10^(-19) )`

`n = 6.25 * 10^(23)`

Therefore,
`6.25 * 10^(23)` electrons are moving through the superconductor per second.
