Question 26
ECMCQ2 marksNeeds review
The circuit shown in the figure is used to provide regulated voltage (5 V) across the 1 kΩ resistor. Assume that the Zener diode has a constant reverse breakdown voltage for a current range, starting from a minimum required Zener current,
mA to its maximum allowable current. The input voltage
may vary by 5% from its nominal value of 6 V. The resistance of the diode in the breakdown region is negligible. 
The value of R and the minimum required power dissipation rating of the diode, respectively, are
