hi i can't understand something in voltage regulators
http://www.youtube.com/watch?v=9FJJre-HG_0&feature=channel
at 11:35 he starts explaning why Vb's equation is like that but i don't get it
at 12:00
he says that Vcc/(R1+R2) gives the current through the two resistors
but how is that possible? I mean in the circuit these two resistors don't have the same current because they are connected in parallel, so why does he say that they have the same current?
i can't get it, i would appreciate any explanation, this is the only thing that i can't understand from his lecture and i really need to understand it because i can't solve problems because of it
thanks in advance
