1. Using the shunt regulator in Figure 4, answer the following: a. When the current through RL increases, does Q1 conduct more or less? Explain. b. Assume the current through RL remains constant and VIN changes by 1 V. What is the change in the collector current of Q1? C. 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?

For the given shunt regulator the conduction of Q1 needs to be obtained for an increase in R_L, 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.

Based on the Bartleby guidelines solved the first three sub parts. Kindly repost the remaining sub parts as separate questions.
