Question

A current of 4Ampere flows through a bulb. How many electrons flow through the bulb in time of 2hours.​

Answer 1

Answer:

1.8*10^22electron

Explanation:

I=q/t

4A=ne/t

4*1=n*1.6*10^-19

4/1.6*10^-19=n

2.5*10^19=n

number of electron flow in 1second =2.5*10^19

nomber of electron flow in 2hrs =2.5610^19*2*3600(1hrs=3600second)

=18*10^21

=1.8*10^22

hope it helps you ♥️♥️
