Q. 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
A) 100 $kilo$-$ohms$ static
B) 1000 $kilo$-$ohms$ static
C) 1000 $kilo$-$ohms$ dynamic
D) 100 $kilo$-$ohms$ dynamic
Explanation
(b) Plate resistance $= \frac{1}{slope} = \frac{1}{10^{- 3} \times 10^{- 3}} = 10^{6}\Omega$
$= 1000\ k\Omega$ (static)
