When you hook up two identical bulbs in series, do they have the same brightness, or is the first one brighter than the other one? a.The top bulb will be brighter because current comes from the positive end. b.The bottom bulb will be brighter because electrons leaves the negative end. c. The two bulbs are the same brightness because current is the same. P=I2R d. The two bulbs are the same brightness because V=IR.
