Answer 2

Answer:

The number of electrons will be given as 4.3 *10^19

Explanation:

Since we know that current I is given by I =Q\t;

where Q= total charge

t= total time

Now the total current can also be given as number of electrons multiplied by total charge on one electron, that is, n*1.6*10^-19 ; where n is total number of electrons.

Therefore,

0.7A= Q\1=n* 1.6*10^-19

From the above equation we get,

n=0.7\1.6*10^-19

n=4.3*10^18
