　　用decreaseincrease,unchange来回答

　　potentialdifference和storedelextricalpotentialenergy是什么区别吗?

　　whichpointsintheuniformelectricfieldbetweentheplatesofthecapacitorlieonthesameequipotential?(图是一个capacitor,上面有4个点,两个是和capacitor平行,还有两个是和capacitor垂直)答案是那两个和capacitor平行的点,为什么?他不是说是uniformelectrifield吗?那不应该是4个点的电压都该是一样的?
