Is Electric Current Scalar or Vector? 

Sometimes it may cause a problem for students to understand that whether the current is a scalar quantity or a vector. Here in this case the question was asked where the student is confusing himself with the same issue. 

Have a look at the question and then read the answers to make yourselves clear too. 

Current has both magnitued and direction but why it is said to be scalar quantity??

Give your suitable explanation

ANSWER 1:

Current is Scalar quantity. Current density(current per unit cross section area of a conductor) is vector quantity

ANSWER 2:

A scalar or scalar quantity in physics is that can be described by a single element of a number field such as a real number, often accompanied by units of measurement (eg. cm). A scalar is usually said to be a physical quantity that only has magnitude, possibly a sign, and no other characteristics. This is in contrast to vectors, tensors, etc. which are described by several numbers that characterize their magnitude, direction, and so on.

The speed of an object is a scalar (e.g. 180 km/h), while its velocity is not (e.g. 108 km/h northward and 144 km/h westward). Some other examples of scalar quantities in Newtonian mechanics are electric charge and charge density.
