Question

Which expression applies Ohm's law to reverse-biased resistance?

Options

• \[r_{rb}=\frac{\Delta I}{\Delta V}\]

• \[r_{rb}=\frac{I}{V}\]

• \[r_{rb}=VI\]

• \[r_{rb}=\frac{V}{I}\]

Answer 1

Ohm's law gives reverse-biased resistance as voltage divided by current: \[r_{rb}=\frac{V}{I}\]. The reverse-bias voltage and current values can be substituted into this expression.
