Q12MHT CET 2026 · 18 APR · SHIFT 2Medium

Junction Transistor

In an NPN transistor, the collector current is 28 mA. If 80% electrons reach the collector, its base current in mA is

Show answer and solution

Answer: (a)

$I_C = 0.8\,I_E \Rightarrow I_E = \dfrac{28}{0.8} = 35$ mA.
$I_B = I_E - I_C = 35 - 28 = 7$ mA.
So the answer is (a) $7$ mA.
