MCQ
The correct curve between voltage gain $\left(A_v\right)$ and load resistance $\left(R_L\right)$ is
- A
- B
- ✓
- D
✓
Answer
Correct option: C.
$\text { According to }\left|A_v\right|=\frac{\mu}{1+\frac{r_p}{R_L}}$as $R$ increases $A$ also increases. When $R$ becomes too high then $A=$ maximum $=\mu$Hence only option $(c)$ is correct.
