Question

Does this basically mean that when you increase the potiential diffrence you are also increasing the current going through the diode... which decreases the resistance because there is more current traveling through the diode?
Basically if I increase the voltage the resistance decreases because there is more current traveling through the material?
The graph pictured is nonomic material is this same concept true with ohmic material?
Please help me understrand this concept better!
I'm thinking of analogy of a pipe with water running through it. If I increased the pressure more water would flow through it decreasing the resistance.. Right?!
I'm mainly confused because the equation is R=?V/I So if the graph was ohmic the slope of ?V and I would be linear so the resistance wouldn't change.
Since the graph pictured is non ohmic the current is increasing at a lot faster rate then the potiential diffrence
Quick Quiz 273 In Figure 27,7h, as the applied voltage increases, does the resi tance of the diode (a) increase, (b) decrease, or (c) remain the same?

Explanation / Answer

the gradient = I/V

R = V/I

here gradient os 1/R

voltage is increasing menas gradient is decreasing
