Question

a conductor carries a current of 3 milli ampere the number of electrons passing through it in 1 minute is abo​

Answer 1

Answer:

soory I don't have any answer

Answer 2

Answer:

10¹⁸

Explanation:

Current, I=3mA=3×10

−3

A

Hence, charge passing per minute, Q=It=3×10

−3

×60=0.18C

And charge on one electron=e=1.6×10

−19

C

Hence, Number of electron=N=

e

Q

⟹N=

1.6×10

−19

0.18

⟹N≈10

18
