Question

current has magnitude+direction+angle of plane on which it acts , so how can electric current be scaler quantity ? In basic study we say it scaler but it's not scaler quantity , can u tell which quantity it is ? ​

Answer 1

Answer:

No. A physical quantity having both magnitude and direction need not be considered a vector. For example, current having magnitude and direction, current is a scalar quantity. The essential requirement for a physical quantity to be considered a vector is that it should follow the law of vector addition.

Generally speaking, the rotation of a body about an axis is not a vector quantity as it does not follow the law of vector addition. However, rotation by a certain small angle follows the law of vector addition and is therefore considered a vector.
