Consider an n-p-n transistor amplifier in commonemitter configuration. The current gain of the transistor is 100 . If the collector current changes by 1 ~mA , what will be the change in emitter current?

Options

  1. A1.1 ~mA
  2. B1.01 ~mA
  3. C0.01 ~mA
  4. D10 ~mA .

Correct answer

B. 1.01 ~mA

Step-by-step solution

Current gain = I_C I_B aligned & I_B= 1 ~mA 100 =10⁻² ~mA . & As I_E= I_B+ I_C=(0.01+1) mA =1.01 ~mA . aligned
