MCQ
The value of $I_c$ for the configuration shown is....$ mA$
- ✓$3.53$
- B$4.68$
- C$2.95$
- D$5.72$
✓
Answer
Correct option: A.
$3.53$
a
$I_{B}=\cdot \frac{V_{C C}-V_{B E}}{R_{B}}=\frac{12 \mathrm{V}-0.7 \mathrm{V}}{240 \mathrm{k} \Omega}=47.08 \mu \mathrm{A}$
$I_{B}=\cdot \frac{V_{C C}-V_{B E}}{R_{B}}=\frac{12 \mathrm{V}-0.7 \mathrm{V}}{240 \mathrm{k} \Omega}=47.08 \mu \mathrm{A}$
$I_{C}=\beta I_{B}$
$=(75)(47.08 \mu A)=3.53 \mathrm{\,mA}$
