Question

Q..The charge on an electron is 1.6 x 10-19C. Find
the number of electrons that will flow per
second to constitute a current of 2A.​

Answer 1

Answer:

The current is defined as rate of flow of charged particle.i.e.

i =

t

Q

Hence the charge flown is,

Q =i t

Hence Q =1.0×1=1C

The charge Q is due to electrons, therefore,

Q =N×e

Here Q =1C

If N is number of electrons passing and e is the electronic charge of value 1.6×10

−19

Then,

N =

e

Q

=

1.6×10

−19

1

=0.625×10

19
