Which collector current does not depend upon the emitter current?

Which collector current does not depend upon the emitter current?

On which of the following does the scale current not depends upon? Explanation: The saturation current does not depends upon the volume of the base-emitter junction. Instead it depends upon the area of the cross section of the base-emitter junction in a direction perpendicular to the flow of current. 8.

What does collector current depend on?

In the active region, the collector current is essentially independent of collector voltage and depends only upon the emitter current. Because adc is, less than one but almost equal to unity, the magnitude of the collector current is slightly less that of emitter current.

Which of the following is not a configuration of BJT?

Detailed Solution. The term “Common” refers to the Common terminal through which input is given and from which output is withdrawn i.e. common terminal between input and output. The term common current is logically incorrect and is not a BJT Configuration.

Why does the emitter current increases with increase in reverse bias at the collector junction?

1)recombination decreases in base leading to more charge carriers reaching collector. This explains your question. 2)The charge gradient increases across emitter junction leading to more emitter current. 3)If reverse voltage is increased further effective base width may become zero causing PUNCH THROUGH.

Why does current flow from collector to emitter in a circuit?

If the voltage at the cathode is higher than the base, this flow of current through the base-emitter junction will cause current to flow from collector to emitter. However in your case, the collector is not at a higher potential than the base, it is at a lower potential.

What is the most important characteristic of BJT?

The most important characteristic of the BJT is the plot of the collector current, the collector-emitter voltage, CE, for various values of the base current, I

What is the relationship between collector current and base current?

Therefore, the collector current is related to the emitter current which is in turn a function of the B-E voltage. The voltage between two terminals controls the current through the third terminal. This is the basic principle of the BJT The collector current and the base current are related by

What is a BJT transistor?

Transistors: Bipolar Junction Transistors (BJT) General configuration and definitions The transistor is the main building block “element” of electronics. It is a semiconductor device and it comes in two general types: the Bipolar Junction Transistor (BJT) and the Field Effect Transistor (FET).
