Junction Transistor

The collector supply voltage is 6 V and a voltage drop across a resistor of $600\ \Omega$ in the collector circuit is 0.6 V, in a circuit of transistor connected in common emitter mode. If the current gain is 20 then the base current is

Show answer and solution

Answer: (b)

Collector current $I_C = \dfrac{V_R}{R} = \dfrac{0.6}{600} = 1 \times 10^{-3}$ A $= 1$ mA.
$I_B = \dfrac{I_C}{\beta} = \dfrac{1}{20} = 0.05$ mA.
So the answer is (b) 0.05 mA.
