Semiconducting Devices Question 277
Question: The slope of plate characteristic of a vacuum tube diode for certain operating point on the curve is $ {{10}^{-3}}\frac{mA}{V} $ . The plate resistance of the diode and its nature respectively
[MP PMT 1990]
Options:
A) 100 kilo-ohms static
B) 1000 kilo-ohms static
C) 1000 kilo-ohms dynamic
D) 100 kilo-ohms dynamic
Show Answer
Answer:
Correct Answer: B
Solution:
Plate resistance $ =\frac{1}{\text{slope}}=\frac{1}{{{10}^{-3}}\times {{10}^{-3}}}=10^{6}\Omega $ = 1000 kW (static).
