In n-p-n transistor circuit, the collector current is $20 m A$ . If $90 %$ of the electrons emitted reach the collector, then the

Options:

Answer:

Solution:

Given, $I_{C} = 20 m A$

$\frac{90}{100} I_{E} = 20$

$I_{E} = 20 \times \frac{100}{90}$

$I_{B} = \frac{10}{100} \times \frac{20 \times 100}{90}$

$= 2.22$

$\approx 2 m A$
