Problem

Two thin, identical copper sheets are stacked so that the top sheet carries a current of

3\,\text{A}

due east and the bottom sheet carries a current of

3\,\text{A}

due west. What is the net electric current through a vertical cross-section that cuts through both sheets? a)

6\,\text{A}

due east b)

3\,\text{A}

due east c)

0\,\text{A}

3\,\text{A}

due west
