The collector supply voltage is 6 V and a voltage drop across a resistor of 600 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

Options

  1. A0.25 mA
  2. B0.05 mA
  3. C0.12 ~mA
  4. D0.02 ~mA

Correct answer

B. 0.05 mA

Step-by-step solution

For collector current, I _ C = Collector voltage Resistance = 0.6 600 =1 ~mA Current gain, = I_C I_B =20 20= 1 I_B . I_B=0.05 ~mA
