4 Ways to Calculate Series and Parallel Resistance - wikiHow
When determining the equivalent resistance for a complex circuit, you must simplify the circuit into groups of series and parallel resistors and then find the equivalent resistance for each group until the circuit is reduced to a single resistance. Work your way backwards finding all potential drops and currents across the individual circuits ...

The resistance of the transistor itself is small compared to the other resistors (X & Y) in the circuit, and makes very little difference in that regard. But, if you make the resistance of X very large, so that the current through that path in the circuit almost stops, then no current will flow through Y either.

The “resistance” of a given piece of material placed between two terminals with difference in voltage V is defined as: V = i * R1, where i is the current which flows between the two terminals when the resistance R is connected. R can always be defined in this way.
