Why doesn't any current flow in BC?- i dont get it
2. Think you linked the wrong question.

If there were a net flow of current from, say, B to C, then the total charge would increase in the CAD loop, and decrease in the B-earth loop. This would produce a voltage tending to stop this hypothesised flow of current, so at some point (quickly, in fact) a state of equilibrium would be reached. And the same argument applies for current in the C-B direction.

why would charge in the b loop decrease?

Current is the flow of charge from one place to another. So if charge flows from B to C, then there will be less charge in the B loop and more in the C loop.

but then an equilibrium would be reached right where it's flowing everywhere?

Having seen your other posts regarding voltage, I suspect that you would benefit from working through a textbook, or website (Khan Academy?), that explains electrical principles in a systematic fashion, rather than trying to work problems at this stage. You seem to be trying to run before you can walk.
