Solid state devices

Questions:

1.  Describe a Thevenin Equivalent Circuit:

2.  Describe how to convert a Thevenin to a Norton Equivalent circuit.

3.  What is meant by “intrinsic” semiconductor material?

4.  What is the difference between “Group 3”  and “Group 5”  elements.

Problems:

1.  Show the Thevenin Equivalent for this circuit.  R1 =  1 KΩ, R2 = 8KΩ, Vs = 50v

2.  Convert this circuit to a Norton Equivalent circuit.  Rs = 2KΩ, Vs = 12v

3.  Show a D.C. battery and resistor connected so the PN junction is forward biased.
