Question

The dynamic resistance of a diode varies as​

Answer 1

Answer:

The ratio of change in voltage to change in current represent dynamic resistance of the diode. It is denoted by r ac . When reverse bias is applied to p-n junction diode, the width of the depletion layer increase and it offers higher resistance to the flow of charge carriers.

Answer 2

The dynamic resistance of a diode varies from a change in voltage to a change in current.

• The ratio of the difference in voltage to change in current exemplifies the dynamic resistance of the diode. It is characterized by ac. When a reverse bias is correlated to the p-n intersection diode, the width of the depletion sheet rise and it gives elevated resistance to the flow of charge carriers.
• The dynamic resistance can be interpreted from the I-V aspect of a diode in forwarding bias. It is interpreted as the ratio of a minor alteration to voltage to a minor alteration in current, i.e. The dynamic resistance of the diode is promptly proportional to the temperature.
