Statement I: If forward current changes by

1.5 \mathrm{~mA}

when forward voltage in semiconductor diode is changed from

0.5 \mathrm{~V}

2 \mathrm{~V}

, the forward resistance of diode will be

1 \Omega

.

Statement II: The forward resistance is given by

R_f=\frac{\Delta V_f}{\Delta I_f}

View answer and explanation

Correct option: D

Statement I is false; Statement II is true

Option D is correct because Statement I is false (the forward resistance is not 1

{\Omega}

) and Statement II is true (the formula for forward resistance is correct).
