Q. If the slope of the characteristics curve of a vacuum tube diode corresponding to some point is $10^{- 3}mAV^{- 1}$, then the plate resistance of diode and its nature are respectively
A) $100\ k\Omega$, static
B) $1000\ k\Omega$, dynamic
C) $100\ k\Omega$, dynamic
D) $1000\ k\Omega$, static
Explanation
(b) $R = \frac{V}{I} = \frac{1}{10^{- 3} \times 10^{- 3}} = 10^{6}\Omega = 1000\ k\Omega.$
