Over what range of input voltages will the arrangement in (a) function as an amplifier?dexterdev said:What is the difference in applying -ve voltage at emitter and +ve voltage at collector in attached circuit image? Really what I think is both circuits in thae image are identical. But then why -VEE?

(b) will function in the same manner, but not with the input/output voltages that cause (a) to work.dexterdev said:the circuit in (a) is basic ECL unit, range of inputs is 2 logic states at input -1.7 V and -0.8 V.
I was asking that what difference (a) has with (b) in voltage supply applied in terms of polarity.
The negative voltage at the emitter is used to control the flow of electrons from the emitter to the collector in a transistor. It helps to regulate the current and amplification of the transistor.
The positive voltage at the collector acts as a barrier to the flow of electrons from the emitter, allowing for better control of the current and amplification of the transistor.
Yes, the polarity of the voltage can be reversed for a transistor. However, it will affect the direction of the current flow and may result in a different output from the transistor.
If both the emitter and collector have the same voltage applied, the transistor will not function properly. The negative voltage at the emitter and positive voltage at the collector are necessary for the proper operation of the transistor.
The voltage at the emitter and collector play a crucial role in determining the gain or amplification of a transistor. By controlling the flow of electrons, the voltages help to regulate the current and ultimately affect the gain of the transistor.
