Question

How many electrons are required to get 1 coloumb of negetive charge?

Answer 1

A collection of 6.2415 × 1018 electrons has a charge of one Coulomb (1/1.60217733x10-19). 1.6 into 10 raise to power -19 no of electrons are present in one coulomb of charge.

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 ✔
