Video Solutions for GATE 2001 ECE : Two Mark Questions (Electron Devices)

1. The transistor shunt regulator shown in figure has a regulated 

    output voltage of 10 volts, when the input varies from 20 volts 

    to 30 volts. The relevant parameters for the zener diode and the 

    transistor are : VZ = 9.5 volts, VBE = 0.3 volts, β = 99. Neglect the 

    current through RB. Then the maximum power dissipated in the 

    zener diode (PZ) and the transistor (PT) are
