PhysicsEasysingle choice

Shown below is a graph of current versus applied voltage for a diode. Approximately, what is the resistance of the diode for an applied voltage of $−1 V$ ?

Options:

Answer:

Solution:

The graph of current versus applied voltage for diode

In this case, at $−1 V$ , current in the circuit is zero.

Hence, according to Ohm's law,

$R = \frac{V}{I} = - \frac{1}{0} = \infty$
