Identify the expression of Ampere-Maxwell s Circuital law. |
| A. | &conint; ( overset{ rightharpoonup}{B}. overset{ rightharpoonup}{dl} ) = <sub>0</sub> (I<sub>C</sub>-I<sub>D</sub>) |
| B. | &conint; ( overset{ rightharpoonup}{B}. overset{ rightharpoonup}{dl} ) = <sub>0</sub> (I<sub>D</sub>-I<sub>C</sub>) |
| C. | &conint; ( overset{ rightharpoonup}{B}. overset{ rightharpoonup}{dl} ) = <sub>0</sub> (I<sub>C</sub>+I<sub>D</sub>) |
| D. | &conint; ( overset{ rightharpoonup}{B}. overset{ rightharpoonup}{dl} ) = <sub>0</sub> (I<sub>C</sub> I<sub>D</sub>) |
