Question: For a triode, at \(V_{g} = - 1\) volt, the following observations were taken \(V_{p} = 75V,I_{p} = 2...
For a triode, at Vg=−1 volt, the following observations were taken Vp=75V,Ip=2mA,
Vp=100V,Ip=4mA. The value of plate resistance will be.
A
25 kΩ
B
20.8 kΩ
C
12.5 kΩ
D
100 kΩ
Answer
12.5 kΩ
Explanation
Solution
rp=Ip1−IP2Vp1−Vp2=(2−4)×10−375−100=12.5 × 103Ω =12.5kΩ.
