1. # Collector Current In Common Emitter Configuration Directly Depends On

## Introduction

In electronics, collector current is a current that flows in the opposite direction of the normal flow of electrons in an electrical circuit. This type of current is used to stabilize voltage and prevent sudden swings in voltage. In this blog post, we will explore how collector current is used in common emitter configurations and how it directly depends on the type of transistor being used. By understanding this, you will be able to select the right transistor for your project without having to guess.

## Collector Current In Common Emitter Configuration Directly Depends On

If you’re looking to configure your collector current in a way that directly depends on the common emitter configuration, you’ll need to use the ohm’s law formula. Refer to the electrostatics article for more information on how this calculation works.

For example, if you have two common emitters with an ESR of 50 Ω and 100 Ω, respectively, using the ohm’s law formula will tell you that your collector current should be: I = V / R

## Conclusion

As you likely know, collector current in common emitter configurations directly depends on the number of emitters in the configuration. This is because each emitter creates a different amount of current that must be added together to get the desired total voltage. To illustrate this point, consider the following circuit: In this circuit, there are three emitters. Each emitter will create a current that is proportional to its voltage (I1=V1/E1, I2=V2/E2, and I3=V3/E3). However, because there are three emitters in this circuit, the total current is still equal to zero (I=0), even though each individual current is greater than zero.

2. In this post, we will study how collector current directly depends on base resistance, collector load resistance and base-emitter voltage.

## Base resistance

The base resistance is the resistance of the base-emitter junction. Base current is directly proportional to base-emitter voltage, and inversely proportional to base resistance.

The collector load resistance is a variable resistor. It’s in series with the collector current, so that means that if you increase the collector current by any amount, then this will cause the voltage across Rc to decrease by an equal amount. This relationship can be summarized as:

• Vbe = IC/(Rb + Rc)

where “Vbe” refers to base-emitter voltage and “IC” refers to collector current. As such, it follows that Rc directly depends on Ic (collector current).

## Base-emitter voltage

In a common emitter configuration, the base-emitter voltage (VBE) is the voltage drop across the base-emitter junction. The collector-emitter voltage (VCE) is the voltage drop across the collector-emitter junction; this is also called “collector cutoff voltage”.

## Emitter current

• Emitter current is directly proportional to the base-emitter voltage.
• Emitter current is directly proportional to the collector load resistance:
• Base current is directly proportional to the base-emitter voltage:

## Collector current directly depends on base resistance.

The collector current is directly proportional to the base resistance.

The collector current is inversely proportional to the collector load resistance.

In this post, we discussed how collector current in common emitter configuration directly depends on base resistance.
