A simple generator has a square armature 9.0 cm on a side. The armature has 95 turns of 0.59-mm-diameter copper wire and rotates in a 0.800-T magnetic field. The generator is used to power a lightbulb rated at 12.0 V and 25.0 W. Part A At what rate should the generator rotate to provide 12.0 V to the bulb? Consider the resistance of the wire on the armature.
