Problem
Two identical 1.5V batteries are connected in series with a light-bulb. A wire of negligible resistance is then connected from the junction between the two batteries directly to the negative terminal of the second battery, as shown in the verbal description. Assuming the batteries are ideal, what is the potential difference across the light-bulb after the wire is added?
(a) 0V
(b) 0.75V
(c) 1.5V
(d) 3.0V
