Drawing power form a 12V car battery, a 9V stabilized DC voltage is required to power a car stereo system, attached to the terminals A and B, as shown in the figure. If a Zener diode with ratings, Vz = 9V and Pmax = 0.27 W, is connected as shown in the figure, for the above purpose, the minimum series resistance Rs must be:-
