Consider the two students below who are discussing the differences observed in the single bulb and two-bulb series circuit. Which student do you agree with? Explain your reasonings. Student 1: In the series circuit, the first bulb uses up half the current and the second bulb uses up the other half. In this way, the bulbs in series are dimmer than the bulb in its own circuit.
Student 2: We know that current is not "used up" in the bulbs so whatever current passes through the battery must also pass through each bulb and return to the battery.
