Question

A conductor carried a current 0.2a. how many electrons will flow in 30 seconds if charge on one electron is 1.6 × 10−19c

Answer 1

as we know , ... I= Q/t

nd Q=ne where n is number of electrons nd e is charge on an electron

Q= ne

therefore.....

I=ne/t

0.5=(n*1.6*10-19 c)/30

uh can now solve it further...hope it helps
