Answer to Question #294347 in Electrical Engineering for joy

Question

Define DC and AC resistance of a diode. Find the DC and AC resistance at

15 μA.

Answer 1

The DC resistance of a diode is similar to AC resistance, but in case of AC resistance the polarity changes with the frequency of the network.

The DC and AC resistance in Ohms is

$$R=V/I=\dfrac V{15\space\mu\text A}.$$
