If the plate resistance oftriode valve is 13 10^6 and amplification factor is 21 . The mutual conductance will be

Options

  1. A1.6 10⁻⁶ mho
  2. B1.6 10^6 mho
  3. C2.6 10⁻⁵ mho
  4. D2.6 10^5 mho

Correct answer

A. 1.6 10⁻⁶ mho

Step-by-step solution

For triode valve, amplification factor, aligned & =r_p g_m & Here, r_p=13 10^6 , =21, g_m=? & g_m= r_p = 21 13 10^6 =1.6 10⁻⁶ mho aligned
