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