Questions
A zener diode in the circuit shown has a knee current of 5 mA and a maximum allowed power dissipation of 300 mW. What are the minimum and maximum load currents that can be drawn safely from the circuit, keeping the output voltage V0 constant at 6 volts ?
detailed solution
Correct option is C
Current from source isI=(9−6)/50=.06A= 60 mA Now, Izmin=5mA and Izmax=Pmax/Vz=300mW/6V = 50 mASo,Lmax=I−Izmin=60mA−5mA = 55 mAAndLmin=I−Izmax=60mA−50mA = 10mATalk to our academic expert!
