Solution

The correct option is A $0.05 m A, 7.5 m A, 150$

For base side;
$V_{B} - 0 = I_{B} \times 200 \times 10^{3} Ω 10 = I_{B} \times 200 \times 10^{3} Ω I_{B} = \frac{10}{200 \times 10^{3}} = 0.05 m A$

For collector side;
$V_{C} - 0 = I_{C} \times 2 \times 10^{3} Ω$
$15 - 0 = I_{C} \times 2 \times 10^{3} Ω \Rightarrow I_{C} = \frac{15}{2 \times 10^{3}} = 7.5 m A ∴ β = \frac{I_{C}}{I_{B}} = \frac{7.5}{0.05} = \frac{750}{5} = 150$
