   Is it the voltage divider and/or the Rc resistor that is responsible for biasing an NPN transistor. Im aware the role each play, but was just wondering which part actually biased the transistor, i wouldve thought both?

   Actually emitter resistor, not collector. In the simple view, the base voltage divider sets the base voltage which in turn sets the emitter voltage 0.7V lower. The equilibrium bias current is then 0.7/Re.
