While a collector to emitter voltage is constant in a transistor, the collector current changes by 8.2 mA when the emitter current changes by 8.3 ~mA . The value of forward current ratio is

Options

  1. A82
  2. B83
  3. C8.2
  4. D8.3

Correct answer

A. 82

Step-by-step solution

aligned & I_c=8.2 ~mA & I_c=8.3 ~mA & Base current I_b= I_c- I_c=8.3-8.2=0.1 ~mA & Forward current ratio = I_c I_b = 8.2 0.1 =82 aligned
