Question

How many electrons should pass through the conductor in 1 sec to constitute 2 Ampere current? Given : Charge on electron = 1.6 × 10⁻¹⁹
13 × 10¹⁸
4.5 × 10¹⁸
6.25 × 10¹⁸
12.5 × 10¹⁸

Answer 1

Answer:

1 Ampere current is by definition 1 Coulomb charge through a cross section of conductor at a given point in one second. So you refer to number of electrons which together hold a charge of 1 Coulomb. This number is 6.24 × 10^18 electrons, which will cross through a section of conductor in one second.
