Question

calculate the current flow in through a conductor.If charge flow in 20 coulamb for a time of 2 second. calculate the number of electrons require for making up this current.​

Answer 1

Answer:

6..25×10 (upper 19*)

Explanation:

Total charge that flows in 2s is given by  

q=It=5×2=10C

Now, charge on one electron is given by e=1.6×10  

−19

C

N= number of electrons

q=Ne

⟹N=  

e

q

​

 

⟹N=  

1.6×10  

−19

 

10

​

 

⟹N=6.25×10  

19
