The amplification factor of a triode valve is 15 . If the grid voltage is changed by 0.3 V , the change in plate voltage in order to keep the current constant (in volt) is :

Options

  1. A0.02
  2. B0.002
  3. C4.5
  4. D5.0

Correct answer

C. 4.5

Step-by-step solution

μ=15,ΔVg=0⋅3∴μ=ΔVpΔVg⇒ΔVp=μΔVg=15×0.3=4.5 V.\begin{aligned} \mu=15, \Delta V_g & =0 \cdot 3 \\ \therefore \quad \mu & =\frac{\Delta V_p}{\Delta V_g} \Rightarrow \Delta V_p=\mu \Delta V_g \\ & =15 \times 0.3 \\ & =4.5 \mathrm{~V} .\end{aligned}
