Question

Which formula gives the dynamic resistance of a diode?

विकल्प

• \[r_{d}=\frac{V}{\Delta I}\]

• \[r_{d}=\frac{\Delta I}{\Delta V}\]

• \[r_{d}=\frac{\Delta V}{\Delta I}\]

• \[R=\frac{V}{I}\]

Answer 1

Dynamic resistance compares a small change in voltage with the corresponding small change in current. Its formula is \[r_{d}=\frac{\Delta V}{\Delta I}\].
