Transistor is itself a transfer of resistance (trans-istor means trans-resistor named by it).
Base or input side high to output side is low resistance offered.

Case 1: If transistor is in OFF condition collector current is High. output voltage Vo = logic 1 = Zero or Min resistance path.
Case 2: If transistor is in ON condition collector current Ic is LOW.because (Ic =Ib+Ie) total current goes to emitter terminal or ground. So output voltage Vo=logic 0 = Max resistance path.
Both cases resistance is variable Min(0) to Max(1).
Case 2: If transistor is in ON condition collector current Ic is LOW.because (Ic =Ib+Ie) total current goes to emitter terminal or ground. So output voltage Vo=logic 0 = Max resistance path.
Both cases resistance is variable Min(0) to Max(1).

We can change the o/p current by changing the i/p resistance so transistor is used as a variable resister.

TRANSICTOR MEANS TRANSFER RESISTOR , IN A TRANSISTOR I/P SIGNAL IS GIVEN TO LOW RESISTANCE PATH , O/P IS TAKEN FROM HIGH RESISTANCE SIDE ,SO RESISTANCE IS VARIABLE IN TRANSISTOR .

by transistor current can be vary so resistance can also varies by increasing or decreasing the battery voltage
