Why a common emitter amplifer is preferred toa common base amplifier

Explanation

### Step-by-Step Solution

1. **Understanding Amplification Factors**:
- In a common emitter amplifier, the amplification factor is represented by beta (β), which is the ratio of the collector current (Ic) to the base current (Ib). Mathematically, it is expressed as:
\[ \beta = \frac{I_C}{I_B} \]
- In a common base amplifier, the amplification factor is represented by alpha (α), which is the ratio of the collector current (Ic) to the emitter current (Ie). It can be expressed as:
