Question

2 ampere of current is flowing through a wire. what is the amount of charge passing through it in 1 min.? also find the number of electrons passed through a cross section of wire in this time...​

Answer 1

Answer:

Amount of charge = 120 Coulomb

No. of Electrons passed = 7.5 * 10^20 electrons

Explanation:

I HOPE THIS WILL HELP YOU

Current = Charge/Time

Therefore Charge = Current * Time

Here Current = 2 A

Time. = 1 min = 60 s

Therefore Charge = 2 * 60

= 120 Coulomb

1 Coulomb charge contains 6.25 * 10^18 electrons

Therefore 120 Coulomb charge contains

= 120 * 6.25 * 10^18 electrons

= 7.5 * 10^20 electrons
