Question

Calculate the number of electrons in 1 Coulomb of charge

Answer 1

hey|!!

here is u r answer...


if a charge is 1 c, then no of electron =1/ 1.6×(10)-19

=.( 10 )19/ 1.6

= 10/1.6 ×(10)18

=6.25 ×(10)18.

thus, 6.25 ×(10)18 electrons taken together constitute 1 coulomb of charge.

ok help u..

Answer 2

We know the formula

Q = I / t

But q is charge and I is its rate

So it means number of charges passing through it per second.

Q = ne which means number of electrons × electronic charge

I = 1C

e = | 1.6 × 10^-19 | - denotes just the magnitude excluding its -ve charge

n = I/t×e

= 1 / 1 × 1.6 × 10^-19
= (10 × 10^18) / 1.6
= ( 100 × 10^18) / 16
= 6.2 × 10^18 number of electrons.....

hope it helps
