Internal capacitance of transistor increases propagation delay.Because charging and discharging of these capacitors will take more time which is not favourable.So always try to select transistors with minimum capacitance.
connect the base of the transistor to a variable resistor and to a normal resistor

Yes, all electronic components have both stray capacitance and stray inductance.
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
RTL logic: NPN transistor. Emitter grounded. Input connected to base through a resistor. Vcc also connected to base through a resistor. If the input is high or open, the transistor is on. If the input is low, the transistor is off. Connect a resistor from Vcc to the collector. The collector is the ouput. You have to play around with resistor values to setup your fan-in and fan-out properties.
Transistor stands for "Transfer Resistor". (Resistor of transference)
The fullform of transistor is transfer resistor.

connect the base of the transistor to a variable resistor and to a normal resistor
if a transistor resistor is connected to the emmiter .
A transistor acts like a resistor when Gate is connected to Source.

resistor
no
It is done in order to protect the transistor from the heavy currents flowing (resistor reduces current flow) into its terminals.
Q1: A PN juncrion has to be reverse-biased for a transiton capacitance to exist. In forward bias there is no depletion layer and the junction conducts, so it does not behave as a capacitance. Q2: In a common-emitter circuit the ouput voltage appears across a resistor connected between the collector and the positive rail (for a normal NPN transistor). Therefore when the current through the transistor increases, there is more voltage drop across this resistor and the collector voltage has to fall.
Yes, all electronic components have both stray capacitance and stray inductance.
