MCQ
Two amplifier are connected one after the other in series (cascade). The first amplifier has a voltage gain $10$ and the second has a voltage gain of $20$. If the input signal is $0.01\, V$, the out $ac$ signal will be........$V$
  • A
    $4$
  • B
    $1$
  • ✓
    $2$
  • D
    $6$
✓

Answer

Correct option: C.
$2$
c
Total gain $=\mathrm{m}_{1} \times \mathrm{m}_{2}=200=\frac{\mathrm{v}_{0}}{\mathrm{V}_{\mathrm{i}}}$

$\mathrm{V}_{\mathrm{o}}=200 \times 0.1=2 \mathrm{volt}$
