Vedclass · Answer

(C) The plate resistance $(r_p)$ of a vacuum tube diode is defined as the reciprocal of the slope of the plate characteristic curve at a given operating point.Given slope = $10^{-3} 	ext{ mA/V} = 10^{-3} 	imes 10^{-3} 	ext{ A/V} = 10^{-6} 	ext{ S}$ (Siemens).Plate resistance $r_p = \frac{1}{	ext{slope}} = \frac{1}{10^{-6} 	ext{ S}} = 10^6 \, \Omega$.$10^6 \, \Omega = 1000 	ext{ k}\Omega$.Since the resistance is calculated at a specific operating point on the curve,it represents the dynamic (or $AC$) resistance of the diode.

The slope of the plate characteristic of a vacuum tube diode for a certain operating point on the curve is $10^{-3} \text{ mA/V}$. The plate resistance of the diode and its nature are respectively:
