What is the relationship between collector current and base current?

What is the relationship between collector current and base current?

The base current controls the collector current when the transistor is in the active region. A transistor is made up of two PN junctions, an emitter junction and a collector junction. The active region is when the emitter junction is forward biased and the collector junction is reverse biased.

How the base emitter current controls the collector emitter current?

The Common Emitter Configuration. One such Common Emitter Amplifier configuration of an NPN transistor is called a Class A Amplifier. A “Class A Amplifier” operation is one where the transistors Base terminal is biased in such a way as to forward bias the Base-emitter junction.

Why does collector current increase with base current in BJT?

The base current in the BJT is due to the recombination of holes and electrons. If we take it the other way round, the larger the base current the greater is the recombination, so the collector current should reduce, but Beta Ic/Ib. …

What controls the collector current?

What is collector base current?

That is, the collector current is approximately. times the base current. Some basic circuits can be designed by assuming that the base–emitter voltage is approximately constant and that collector current is β times the base current.

Why does collector current depend on base current?

If the electron supply to the base (base current) is reduced then base becomes negative and attracts less number of hole due to which net flow of hole from Emitter to Collector decreases and the collector current decreases. Thus Collector current is controlled by the Base current. , student of electronics since 1999.

What happens to the collector current when the base current increase?

An increase in base current means more bias to the transistor which further means collector current will also increase but till the limiting value of the transistor parameters. However, if you try to push more current to the base, collector current would no more increase but the transistor may break down.

Why collector current is more than base current?

Answer: Explanation: Base is much narrower and thinner than collectors,hence the majority of charge carriers are received by collector. Hence,collector current is greater than base current.

What is the effect of base current on collector current?

Hello, an increase in base current means more bias to the transistor which further means collector current will also increase but till the limiting value of the transistor parameters. However, if you try to push more current to the base, collector current would no more increase but the transistor may break down.

Which current controls the collector current in a transistor?

The base current controls the collector current when the transistor is in the active region. A transistor is made up of two PN junctions, an emitter junction and a collector junction.

What is the base current of a transistor?

, student of electronics since 1999. The base current controls the collector current when the transistor is in the active region. A transistor is made up of two PN junctions, an emitter junction and a collector junction. Transistors are controlled by a voltage applied between the emitter and base.

What is the relationship between base current and B-E voltage?

3 Answers. An increase in this voltage results in increased currents in both the base and the collector, and indeed, an increase in base current causes an increase in B-E voltage. But the base and collector currents generally have a fixed ratio to each other for any particular transistor under a particular set of conditions,…
