Student 1: Student 2: (a) (b) \"The current through the battery in each circult is the same. In cireult b the current from the battery ls divided between the two bulbsso each bulb has half the current through it that the bulb in circuit a has through it.\" \"We know the current through each of the bulbs in circult b ls the same as through the bulb in circuit a. That's because the bulbs are all about the same brightness and bulbs that are equally bright have the same current through them. So the flow through the battery In circult b ls more than that through the battery in circult a.\
