Question

calculate the number of electrons consistuting 1 coulomb of charge.

Answer 1

Hello..
♪＼(*＾▽＾*)／＼(*＾▽＾*)／

Quantisation of Charge :-

  Q = ne

 1 coloumb of Charge = n . 1.6*10-19

   =1/ 1.6*10-19 = n

  6.25*1018 = n

thank you ☺

Answer 2

Given that

Charge (Q) = 1 C

Electron (e) = 1.6× 10^-19

Number of electron (n) = ?

Q= ne

1 C = n × 1.6×10^-19 C

n = 1/(1.6×10^-19)

n = 6.25 × 10^18 electron
