Question

The dynamic resistance of a diode is defined as:

Options

Choose one · Correct answer highlighted

Î” I / Î” V V / I I / V Î” V / Î” I Correct

Explanation

Dynamic resistance ( r_d ) is the ratio of a small change in voltage ( Î” V ) to the corresponding small change in current ( Î” I ), i.e., r_d = Î” V / Î” I, reflecting the diode's behavior under small signal variations.
