The circuit shown in the figure is used to provide regulated voltage (5V) across the resistor. Assume that the Zener diode has a constant reverse breakdown voltage for a current range, starting from a minimum required Zener current, its maximum allowable current. The input voltage may vary by 5% from its nominal value of 6V. 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
