In an $n - p - n$ transistor circuit, the collector current is $10 mA$ . If $90 %$ of the electrons emitted reach the collector

Options:

Answer:

Solution:

As $I_{C} = 90 % o f I_{E}$ (according to questions)

$\Rightarrow 10 mA = \frac{90}{100} I_{E}$

Or $I_{E} = \frac{10 \times 10}{9} \approx 11 mA$

$I_{B} = I_{E} - I_{C} = 11 mA - 10 mA = 1 mA$
