Expert Solution

Step 1: Parameter needs to be calculated

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.
