Threshold voltage - Threshold voltage of transistor is the minimum gate to source voltage that is needed to create a conducting path between the source and drain terminals. It is an important factor to maintain power efficiency. (Measured in Volt)
Change in collector resistance - Change in collector resistance is the increment or decrement in resistance passing through the collector region. (Measured in Ohm)
Collector Resistance - Collector Resistance, Rc helps to set the transistor at the "operating point" of the amplifier. The purpose of the emitter resistor Re is to prevent "thermal runaway". (Measured in Ohm)
