If the slope of the characteristics curve of a vacuum tube diode corresponding to some point is

{10^{ - 3}}\mathrm{mA}{\mathrm{V}^{ - 1}}

, then the plate resistance of diode and its nature are respectively

View answer and explanation

Correct option: B

1000\mathrm{\;k\Omega }

, dynamic

Option B (

1000\mathrm{\\;k\Omega }

, dynamic) is correct because the plate resistance is the inverse of the slope of the characteristic curve, and it represents a dynamic resistance.
