Question

Find the number of electrons that flow per second to constitute a current of 2A ?​

Answer 1

Answer:

I= 2A

time = 1 sec

find no. of electrons.

I = Q/ T

I×T= Q

I× T= n.e

I×T/e= n

2A ×1 / 1.6× 10^-19= n

2A × 10^19/1.6=n

2× 10^18×100/16= n

2× 10^18×6.25=n

12.5× 10^18=n

1.25×10^19=n

1.25×10^19 electons Answer
