The wire layout we used was supposed to be in a straight line from top to bottom. We used the wires connected to the bulb to connect the bulbs to each other instead of cutting pieces of wire. We used the battery and wires to connect the bulbs in a series. Our project has electrical tape on it to help keep the bulbs in a straight line. Three of the bulbs are dimmer than the other three. I chose series circuit diagram because it's slightly easier to calculate the resistance and current.
