Question

calculate the number of electrons that flow per second to constitute a current of 2 ampere.​

Answer 1

Answer:

1 Ampere = 1 Coulomb /1 Second

Charge on 1 electron = 1.6 x 10^-19 Coulomb

By unitary method,

If 1.6 x 10^-19 Coulomb / Second (Ampere) = Current by 1 electron

then, 1( Coulomb / Second) or (Ampere) = 1 / (1.6 x 10^-19) electrons

i.e, 6.25 x 10^18 electrons.
