In the circuits below, the batteries are ideal 12 V batteries. When the switch S is closed in circuit (a) . Does the potential difference across R1 increase, decrease, or stay the same? Explain. Does the current through the battery increase, decrease, or stay the same? Explain. When the switch S is closed in circuit (b), Does the potential difference across R1 increase, decrease, or stay the same? Explain. Does the current through the battery increase, decrease, or stay the same? Explain.

Explanation / Answer

a)
i) remains the same, because ot is parallel to battery

ii) increases, Because Rnet decreses

b)
i)remains the same, because Rnet decreases, i ancreses

ii) increases, Because Rnet decreses
