Response to the following problem :
a. Using the axes of Fig. , sketch the characteristics of a device that has an internal resistance of 500 Ω from 0 to 1 V and 50Ω between 1 V and 2 V. Its resistance then changes to -20Ω for higher voltages. The result is a set of characteristics very similar to those of an electronic device called a tunnel diode.
b. Using the above characteristics, determine the resulting current at voltages of 0.7 V, 1.5 V, and 2.5 V.
