Common emitter transistor

Here a simplified example.

If you increase V1 then the voltage Vce will also increase.
The voltage Vbe can only vary a very little bit. For now see it as stable at 0,6V.
That makes  Vcb = Vce - 0,6V.  Therefore if Vce increases then Vcb increases as well. The increase of Vce and Ib is therefore a result of increasing V1.
