Question

A conductor has a negative charge of 1.6 coulomb. How many excess electrons does it have? Charge of an electron is epsilon = 1.6 * 10 ^ - 19 * c​

Answer 1

Answer:

Answer

We know that

                   I=  

t

Q

​

 

⇒1A=  

1s

Q

​

 

⇒Q=1C

Now, charge of one electron is 1.6×10  

−19

 coulombs

Therefore, in 1 coulomb charge, number of electrons =  

1.6×10  

−19

​

=0.625×10  

19

 

=6.25×10  

18
