Question

1. What do you mean by common emitter configuration ?​

Answer 1

$\huge\star{\red{\underline{\mathfrak{Answer!!}}}}$

Definition: The configuration in which the emitter is connected between the collector and base is known as a common emitter configuration. The input circuit is connected between emitter and base, and the output circuit is taken from the collector and emitter.

Question:What do you mean by common emitter configuration ?

Answer

• Definition: The configuration in which the emitter is connected between the collector and base is known as a common emitter configuration. The input circuit is connected between emitter and base, and the output circuit is taken from the collector and emitter. Thus, the emitter is common to both the input and the output circuit, and hence the name is the common emitter configuration.
• The common emitter arrangement for NPN and PNP transistor is shown in the figure below

• Base Current Amplification Factor (β)

The base current amplification factor is defined as the ratio of the output and input current in a common emitter configuration. In common emitter amplification, the output current is the collector current IC, and the input current is the base current IB.

• In other words, the ratio of change in collector current with respect to base current is known as the base amplification factor. It is represented by β (beta).
