​please answer de do urgent

Answer 1

Explanation:

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

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 = Q

e

= 1

1.6×10 ^19

=0.625×10^19
