Yes, even though you shoulders be perfect, I insist that you have a badic idea about static charges.
As you know, current is all about moving charges.
This chapter is very easy and very interesting.
You'll learn all about the real electricity, drift velocity of electrons,resitance and conductance and many other things.
Just start and read through the new chapter catefully.
If you find any difficulty, you can refer the electrostatics or ask your doubts, directly in the portal.
