diodes follow an exponential curve meaning non linear in nature. by using Boltzmann formula an impedance can be calculated. That would be the AC Resistance the dc resistance on any device is the voltage drop divided by the dc current.

What is static and dyanmic reactance?

The static resistance which is calculated from the static ch. of doide is the dc resistance offered by the diode. dynamic ch. of the diode describes the diode's behavior when the applied voltage is fluctuating,or ac, thus the dynamic resistace is simply the ac resistance offered by the diode.akhil gopalpunnapra


What is the behavior of a forward and reverse biased diode?

Forward Resistance:def: It is resistance offered by diode to the forward bias is known as forward resistance.This resistance is not the same for the flow of DC as for the changing current. Accordingly this resistance is of two types :1. DC FORWARD RESISTANCE.2. AC FORWARD RESISTANCE.1. DC forward resistance: It is the opposition by diode to the DC. It is measured by the ratio of DC voltages across the diode to the resulting DC current through it.2. AC forward resistance: It is the opposition offered by the diode to the changing current. It is measured by the ratio of change in voltage across diodes to the resulting change in current through diode. The AC forward resistance is more significant as the diodes are generally used with alternating voltage.Reverse Resistance:def: The resistance offered by the diode to the reverse bias is known as Reverse Resistance. It can be DC reverse resistance or AC reverse resistance depending upon whether the reverse bias is direct or changing voltage. Idealy the reverse resistance of a diode is infinte however in practice the reverse resistance is not infinite because for any value of reverse bias, there does exist a small leakage current. It may be emphasized their that reverse resistance is very large compared to the forward resistance.These Definitions are from PRINCIPLES OF ELECTRONICS by V.K MEHTA and ROHIT MEHTA


What is ac resistance of a diode?

ratio of ac voltage applied across the diode to the ac current flowing through it


How does pn junction diode can be used as an electronic switch?

A diode allows current to flow in only one direction. If the current is flowing, the diode has a low resistance and it behaves like a wire or a switch in the on position. If the voltage across the diode is reversed, no current flows and the diode has a very high resistance. It behaves like a switch in the off position. DC voltages are used to switch the diode on or off. The signal that is being switched is usually an AC audio or radio signal. Capacitors block DC but pass AC signals. By combining diodes and capacitors, the AC and DC signals are kept separate and the switch can be built.


How does a diode change from AC to DC?

it clips all the bottom voltage off the sine wave,to get steady dc voltage you will need to clean up the ripple to get good voltage regulation <><><> A diode does not change AC to DC, but it does allow alternating current to flow in only one direction. A diode (or often 2 or 4 diodes) with a filter can be used to rectify AC into DC.

What is AC forward resistance?

AC forward resistance refers to the effective resistance experienced by an alternating current (AC) signal as it passes through a diode in the forward-bias direction. It is influenced by the diode's intrinsic resistance, as well as the capacitance and inductance of the diode. The AC forward resistance can impact the efficiency and performance of the diode in rectifying AC signals.

How do you find the ac resistance of a diode?

The ac resistance of a diode is found using the equation: (The change in Vd)/(The change in Id) An easier was is to use the Equation: 26mV / Id. This is a general form as the ac resistance of a diode change as the temperature changes.


How diode convert pure ac to pure dc?

You can't convert ac to pure dc with diode only. The easiest way to convert ac to dc by with diode is by using rectification, it consist of at least 2 diodes (half wave rectifier) and (capacitor is to "smoother" the wave).
