What is the emitter base collector in 2N5777 photo transistors?

1st pin is emitter then collector and base


Why output of common emitter amplifier is inverted?

In a common emitter amplifier, the base-emitter current causes a corresponding collector-emitter current, in the ratio of hFe (beta gain) or collector resistance over emitter resistance, which ever is less. Since this ratio is usually greater than one, the differential collector current is greater than the differential base current. This results in amplification of the base signal. As you increase the base-emitter current, the collector-emitter current also increases. This results in the collector being pulled towards the emitter, with the result that the differential collector voltage decreases. This results in inversion of the base signal.


What are the parameters of a transistor?

# parameter are usually the base current ib,collector current ic,emitter current ie,collector emitter voltagevce,base emitter voltagevbe,collector base voltagevcb which decide the operation &output of the transistor


What is transistor action?

The transistor has three regions, emitter,base and collector. The base is much thinner than the emitter while the collector is wider than both. However for the sake of convenience the emitter and collector are usually shown to be of equal size. The transistor has two pn junctions that means it is like two diodes. The junction between emitter and base may be called emitter-base diode or simply the emitter diode.The junction between base and collector may be called collector-base diode or simply collector diode. The emitter diode is always forward biased and the collector diode is always reverse biased.


How does emitter current is equal to base current and collector current?

Consider that current flow "enters" at the emitter and "exits" at the collector and base. Now, IE = IB + IC. Alternately, current "enters" at the collector and the base, and "exits" at the emitter. Now, IE = IB + IC

Why is collector current slightly less than emitter?

The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.


Why is collector current increased slowly with the increase of collector to emitter voltage of a common emitter?

The percentage of doping in emitter is higher than collector region.hence large current is flow to emitter than collector.


Why is collector wider than emitter and base?

actually in the case of transistors there are two concepts that are often misleaded those are 1. order of doping 2. order of the size of various regions order of doping emitter>collector>base order of size of various regions collector>emitter>base now the reason for this as CB junction is reverse biased more heat is dissipated at this junction so if the collector junction has large area the heat can be dissipated easily there by the transistor is saved from the burning of CB junction
