What Is the Slope Resistance of a Zener Diode?

Click For Summary
The slope resistance of a Zener diode refers to the change in voltage over the change in current in the reverse bias region, representing a form of resistance. This slope is derived from the current versus voltage plot, where the Zener diode begins to conduct in reverse bias. It is not a fixed value but can be averaged over a specific range of reverse bias conditions. The concept helps in understanding the diode's behavior in voltage regulation applications. Overall, slope resistance is a crucial parameter for analyzing Zener diode performance in circuits.

what is the mean of "slope resistance" of zener diode? Its parallel to diod or series?

Look at the plot of the Current versus Voltage for the diode in forward and revers bias. In reverse bias, where the Zener diode starts to conduct, there is a slope to the curve. That slope can be thought of as a "resistance", if you linearize (average) it over some range of reverse bias.
 
Thread 'I thought it was only Amazon that sold unsafe junk'
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
