Q5. In the shunt regulator of Figure 5: a. When the load current increases, does conduct more or less? Why? b. With a constant input voltage of 17 V, the load resistance is varied from to 1k0 to 1.2kn. Neglecting any change in output voltage, how much does the shunt current through Q, change? c. If the maximum allowable input voltage is 25 V, what is the maximum possible output current when the output is short-circuited? What power rating should R, have?
