You have a 6-volt battery (assumed ideal) and a 1.5-voltflashlight bulb which is known to draw 0.5A when the bulb voltageis 1.5V (see figure below). Design a network of resistors to gobetween the battery and the bulb to give vs=1.5V when the bulb isconnected yet ensures that vs does not rise above 2V when the bulbis disconnected.
