1. Using the shunt regulator in Figure 4, answer the following:
C.
Normal
No Spacing
When the current through RL increases, does Q1 conduct more or less? Explain.
●
D
5.1 V
b. Assume the current through RL remains constant and VIN changes by 1 V. What is the
change in the collector current of Q1?
d. Assume the maximum allowable input voltage is 25 V.
With a constant input voltage of 17 V, the load resistance is varied from 1.0 k to 1.2 kn.
Neglecting any change in output voltage, how much does the shunt current through Q₁
change?
What power rating should R1 have?

Step 1: Parameter needs to be calculated
For the given shunt regulator the conduction of Q1 needs to be obtained for an increase in RL, For constant load current, the change in collector current needs to be calculated and the change in shunt current through Q1 needs to be calculated.
