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.

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.
What is dynamic resistance of diode?
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).
Difference between static and dynamic charercteristic of motor?
I think you are talking about the study of the electrical system for motor starting in ETAP (or any such software). Here are the answers:1. When do we use Static and Dynamic motor starting?If you know the Motor torque characteristics, Load torque characteristics and the inertia information of the motors, bearings and loads, you can do the Dynamic motor starting study. Otherwise, do the Static motor starting study - it simply needs the starting time and the locked rotor current of the motor.2. What is the difference between the two?(1) The Dynamic motor starting develops the motor starting current characteristics based on the motor starting torque, load torque and the inertia, while the starting current remains flat at locked rotor current during the starting time for Static acceleration. (See the previous posting http://cr4.globalspec.com/thread/42981 , comment # 2 for detail how the starting time is calculated for Dynamic acceleration).(2) Dynamic starting acceleration requires additional data than the Static acceleration.(3) The Dynamic acceleration calculates the acceleration time and current from the input data, while the Static acceleration assumes you know the starting time and current.(4) For Dynamic acceleration, the starting current is not 100% flat during the starting time, but in Static acceleration it is flat.(5) Static acceleration is simple, Dynamic acceleration is rather complicated.3. Can we evaluate the system using Static only not dynamic?Yes. Make sure you have the correct information for motor locked rotor current and the stating time for the load.Go the ETAP tutorial site (http://www.etap.com/training/tutorials-training-videos.htm) and see the tutorial #12 (Dynamic Acceleration) and #13 (Static acceleration).curtesy msamd
What is the difference between an short circuit and a closed circuit?
You know there is a differnce. The dynamic short circuit is dynamic and the static short circuit is static. It's common sense really.dyanamic means when due to some external source theresistance becomes zero ,can be through anythin due to high supply of current or anything,the current in that circiut becomes infinite and that result s in short circuiting. Static short circuit means when through the different changes in the voltage makes the resistance zero and current infinite , V = I/R WHERE R= 0 AND CURRENT BECOMES INFINIT AND THAT RESULT IN A SHORT CIRCUIT

The four different types of stretching are?
static, dynamic, lateral and resistance.
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
