In the C B mode of a transistor, when the collector voltage is changed by 0.5 volt, the collector current changes by 0.05 mA . The output resistance will be

Options

  1. A10 k
  2. B20 k
  3. C5 k
  4. D2.5 k

Correct answer

A. 10 k

Step-by-step solution

Here: aligned & V_c=0.5 volt , & I_c=0.05 ~mA =0.05 10⁻³ ~A aligned Output resistance is given by aligned R_ out & = V_c I_c & = 0.5 0.05 10⁻³ =10^4 =10 ~K aligned
