Question

How many electron passes through o.1 coloumb of charge?

Answer 1

1.6x10to the power-20

Answer 2

Answer :-

One electron possesses a charge of

1.6 ×10-19C,

i.e., 1.6 ×10-19C of charge is contained in 1 electron.

∴ 1 C of charge is contained in

1/1.6 x 10-19 

= 6.25 x 1018 

= 6 x 1018

Therefore, 6 x 1018 electrons constitute one coulomb of charge.

Note :- You can Write 1018 as 10^18 also ✔
