Can i ask? Doesn't it have 3 operation regions? Its a cut-off, an active one, and the saturation one... Well as an electronic enthusiast, and still a long way to go, i guess its active region!The name transistor is a contraction of "transfer resistor".
Of course the transistor can be used as a resistor that is exactly what it is - a controllable resistance.
The resistance is between the collector and emitter - we control it by applying suitable signals to the base.
However there is no requirement for that resistance to be high or low, it is up to us to set its value. And yess transistors can be cheaper to fabricate on chip than resistors.
One question for you
The transistor has two regions of operation the active region and the saturated region, which do you think applies in this case?
