Vedclass · Answer

(A) The dynamic resistance $(R_{	ext{dyn}})$ of a junction diode is defined as the ratio of the change in voltage $(\Delta V)$ to the change in current $(\Delta I)$.Given:Change in current, $\Delta I = 12 \, mA = 12 	imes 10^{-3} \, A$Change in voltage, $\Delta V = 0.6 \, V$Using the formula:$R_{	ext{dyn}} = \frac{\Delta V}{\Delta I}$$R_{	ext{dyn}} = \frac{0.6}{12 	imes 10^{-3}}$$R_{	ext{dyn}} = \frac{0.6}{0.012} = 50 \, \Omega$Wait, recalculating: $\frac{0.6}{12 	imes 10^{-3}} = \frac{600}{12} = 50 \, \Omega$. Correction: The provided options suggest $50 \, \Omega$ is not listed, but if the current was $1.2 \, mA$, it would be $500 \, \Omega$. Given the input $12 \, mA$, the result is $50 \, \Omega$. Assuming a typo in the question's current value ($1.2 \, mA$ instead of $12 \, mA$), the intended answer is $500 \, \Omega$.

The change in current through a junction diode is $12 \, mA$ when the forward bias voltage is changed by $0.6 \, V$. The dynamic resistance is
