In a transistor, when the emitter current changes by 9.85 mA , the collector current changes to 9.5 ~mA . Then the base current is

Options

  1. A0.05 ~mA
  2. B0.85 ~mA
  3. C0.8 ~mA
  4. D0.35 ~mA

Correct answer

D. 0.35 ~mA

Step-by-step solution

aligned & I _E=9.85 ~mA & I _ C =9.5 ~mA & I _E= I _B+ I _ C aligned Base current, I_B=I_E-I_C=9.85-9.5=0.35 ~mA
