The Current-Voltage relationship of a diode is not constant (not a straight line) and hence the resistance cannot be measured. Due to this non-linear nature of the the curve, there exists a unique value of resistance at every point of the curve which is called dynamic resistance (not static of constant resistance).
The dynamic resistance equals the change in voltage divided by the change in current, when the voltage is changed by a small amount. In other words it is the slope of the graph of voltage against current. The dynamic resistance is different at different current values.
About 30 years ago, and I do not remeber the brand or maker, there was a digital multimeter that DID measure dynamic resistance in diodes. It was a God Send for testing diodes in circuit. Diodes only conduct in one direction, so the device would show an open in one direction and a resistance under 1000 ohms on the other or a short (0 ohms).

Why the dynamic resistance of a zener diode different from its static resistance?
The dynamic resistance of a diode, be it zener or otherwise, will be different from its static resistance because a diode is not a resistor, and resistance is not a function of current flow. It is a diode, and a diode has its own characteristic voltage to current curve, forward and, in the case of a zener, reverse.
Dc resistance of diode is a static resistance b dynamic resistance c high resistance d zero resistance?
B - Dynamic resistance
What is Zener resistance of the Zener diode?
zener resistance of a zener diode is the resistance of the zener diode but which is the resistance of a diode
What is meant by static and dynamic resistance?
static resistance: This is measured when diode id forward biased and input is a D.C signal. The ratio of voltage applied to the current flowing through diode gives static resistance Dynamic resistance : this is measured when input is A.C signal. since A.C signal varies continuously the resistance offered also changes continuously. the ratio of change in voltage to change in current gives dynamic resistance.
Infinite resistance in one direction of Diode?
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode

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

The bluk resistance of a diode depends on?
Bulk resistance of diode depends on how it is biased. The bulk resistance of a diode is the approximate resistance of the diode when it is forward biased.
Infinite resistance in one direction of Diode?
After isolating the diode from the circuit, the diode shows infinite resistance in one direction and low resistance in the other direction. The diode
What is meaning of dynamic elements in electronics?
Dynamic element term is arises on the domain of digital to analog conversion in the field of electronics. if you are looking for dynamic microphone it means this converter applied sound vivration to electrical signal. Dynamic term also arise in the field of diode static and dynamic resistance.
Can you use resistance in place of diode in clipping circuits?
no we not use resistance in place of diode.
