The graph in figure a shows the current I in a diode as a function of the potential difference ∆V across the diode. Figure b shows the circuit used to make the measurements. The symbol represents the diode.
(a) Using Equation 17.3, make a table of the resistance of the diode for different values of ∆V in the range from –1.5 V to +1.0 V.
(b) Based on your results, what amazing electrical property does a diode possess?
