Question

hello mates✌️✌️

Good morning..☀️☀️

plz answer the below question

if a current of 3.2 ampere per second flows through a conducting wire calculate the number of electrons passing through the wire.

I will mark your answer as brainliest answer ☑️☑️

Answer 1

Hi,

Use formula (I=ne/t)

Here, I=current,

n=number of electron

e=electron =1.6 x 10¯¹9 C

Then calculate,

I=ne/t

10= n x 1.6 x10¯¹9 / 1

n= 10/1.6 x 10¯¹9

n = 6.25 x 10¹9.

Answer 2

hey mate here is your answer✨✨

I=3.2A. , e=1.6×10^-19

I=Q/t

Q=It
Q=3.2×1
Q=3.2

Q=ne
3.2=n×1.6×10^-19
3.2/1.6×10^-19=n
n=2×10^19
n=0.2×10^20

therefore number of electron is 0.2×10^20

hope it's helpful___________
