Answer:

q=6*10^-4

n=3.75x10^-15

Explanation:

Given :

Current , I = 20 mA .

Time , t = 30 s .

amount of charge(q)=ixt

                              =20x10^-6 x30

                               =6x10^-4 columbs

number of free electrons=(6x10^-4)/1.6*10^-19

                                        =3.75x10^15
