In a transistor, connected in common emitter mode `R_(0)=5kOmega," "R_(i)=1kOmega," "I_(C)=1mA,I_(B)=40muA`. Find the voltage gain.

Explanation

To find the voltage gain (AV) of a transistor connected in common emitter mode, we can use the following formula:

\[ A_V = \beta \cdot \frac{R_0}{R_i} \]

Where:
- \( \beta \) (current gain) is given by the ratio of collector current (\( I_C \)) to base current (\( I_B \)):
