When plate voltage in diode valve is increased from 100 V to 150 V. Then, plate current increases from 7.5 mA to 12 mA, then dynamic plate resistance will be

Options

  1. A10 k
  2. B11 k
  3. C15 k
  4. D11.1 k

Correct answer

D. 11.1 k

Step-by-step solution

aligned Plate resistance & = V_ P₂ - V_ P₁ j_ P₂ - j_R & = 150-100 (12-7.5) 10⁻³ = 50 10^3 4.5 aligned =11.1 k
