When the collector current in a transistor in zero the transistor is?
When the collector current in a transistor in zero the transistor is?
Cut-off Region Here the operating conditions of the transistor are zero input base current ( IB ), zero output collector current ( IC ) and maximum collector voltage ( VCE ) which results in a large depletion layer and no current flowing through the device. Therefore the transistor is switched “Fully-OFF”.
Why is Collector current less?
The base contains more holes than electrons. As the direction of current is opposite to the flow of electrons we can understand that current from the emitter is conducted to the base and the collector. Hence, the collector current will always be slightly less than the emitter current.
Why is Collector current?
Collector Current It increases for larger emitter currents because the larger number of electrons injected into the base exceeds the available holes for recombination so the fraction which recombine to produce base current delines even further.
What is a collector circuit?
The Common Collector Amplifier is another type of bipolar junction transistor, (BJT) configuration where the input signal is applied to the base terminal and the output signal taken from the emitter terminal. Thus the collector terminal is common to both the input and output circuits.
What is the relationship between collector current and emitter current?
What is the relationship between the base-emitter and collector-emitter voltages of a bipolar transistor? Generally, the current that flows from the emitter to the collector or vice versa is the base current times the DC current gain (hFE).
Which of the following has highest current gain?
Explanation: Current gain in CE configuration is β = ΔIC/ΔIB. IC >> IB , hence it is maximum.
Is collector current equal to emitter?
In any configuration biased in the linear region, collector current is almost equal to emitter current. This is because of the large current gain of a bipolar transistor. So very little base current causes a very large collector to emitter current.
