Question

Is electric current a scalar or vector quantity? Sate the smaller unit of current.

Answer 1

Answer:

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. Also, Current is written as the dot product of Current Density vector and the Area vector.

cgs unit is biot

Answer 2

Electric current is a scalar quantity. Smaller units - Coulomb or esu

Explanation:

Electric current is the measure of how much charge flows through a particular area. It is a scalar quantity.

Electricity has both magnitude and direction, but it does not follow the Triangle law of vector addition. So it is not considered a vector quantity despite having both magnitude and direction.

The smallest measurable unit of charge is Coulomb or electrostatic unit, esu.
