Electric current is denoted by the alphabet “i”.

Why current is scalar and current density is vector. In the case of electric current , although it has direction, but when the two current collides or meets their sum is equal to the algebric sum and not vector sum (i.e it. Is current a scalar or a vector quantity?topics discussed:1. That’s why we can say that electric current is a scalar quantity.

Whenever two currents meet at a junction in the terms of electrical current, the resultant. Hi, current represents the direction of the flow of charged carrier in the conductor and is considered as a scalar quantity. Current is scaler because it is produced due to drift movement of charge and current density is vector because current per unit area.

The quantity should obey the laws of vector addition. The standard unit of electric current is ampere. Is current density a scalar or a vector quantity?

Actually current is not a scalar quantity because it can not completely defined by magnitude only, it is not a vector quantity also because it doesn't obey commutative and. The main reason to consider the electric current as a scalar quantity is that it doesn’t apply to vector summation. Electric current is a scalar quantity.

Also, current is written as the dot product of the current density. Current density is a vector quantity because it is. For a physical quantity to be termed a vector quantity, having magnitude and direction is not enough.

Current density is a vector quantity. Any physical quantity is defined as a vector quantity when the quantity has both magnitude and direction but there. Discussion on why current is a s.
