Yes, since more electrons are flowing, there is a greater flow rate of charge; aka, current; and so the signal is amplified. The only thing is, the main voltage with the collector does not add to the small current that passes through. Rather, the voltage is there to keep the electrons moving after they go through the depletion zone of the transistor.

The apparent brightness of an incandescent bulb is a very strong function of the temperature of the filament, because it behaves approximately like a black body. Thus, much of the power emitted will be in the IR. The black body spectrum for different temperatures can be found, for example at wikipedia: Note this is a visual representation of Planck's law. ...

according to conversational current, electric current is said to move from the positive terminal to the negative. This is not correct. The conventional current defines positive current in the direction of flow of positive charge, or opposite the direction of flow of negative charge. But conventional current can flow either from a higher potential to ...

I think everyone must be right. (I'm certainly not going to contradict two-time physics Nobel Laureate John Bardeen.) Schottky diodes have very short reverse-recovery times (switching from the conducting to the blocking state), so there can't be any significant minority-carrier currents, because it's extracting those minority carriers that slows down the ...
