Electric current has both magnitude & direction but, why it is not a vector quantity |
| Answer» It may seem that current is a vector because it have a magnitude and a direction. But the thing is, a vector always obey the law of addition of vectors. Since current doesn\'t obey it and it follows algebraic addition, current is a scalar. | |
