ConceptSemiconductor Diode

#### Question

The dynamic plate resistance of a triode value is 10 kΩ. Find the change in the plate current if the plate voltage is changed from 200 V to 220 V.

#### Solution

Given:-

Plate resistance,

r_p=10kOmega=10^4Omega

Change in plate voltage,

deltaV_p=220-200=20V

Plate resistance at constant grid voltage is given as:-

$r_P = \left(\frac{\delta V_P}{\delta I_P}\right)_{V_G = Constant}$

$\Rightarrow \delta I_P = \frac{\delta V_P}{r_P}$

$\delta I_P = \frac{\delta V_p}{r_P}$

$\delta I_P = \frac{20}{{10}^4} = 0 . 002 A = 2\text{ mA}$

Is there an error in this question or solution?
