Question

The number of electrons passing through a sector of wire per 2second when the wire carries a current of 5ampere
​

Answer 1

Explanation:

Q = IT

= 5 × 2

= 10C

now charge on ech electron is 1.6 x 10^-19 C

so cahrge on x electrons is 10 C

thus x = 10/1.6 x 10^-19 = 6.25 x 10^19 electrons
