# Is electric current is scalar or vector quantity?

Contents

Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction.

## Why electric charge is a scalar quantity?

Nothing is a vector until defined with a direction.

Electric charge is a scalar quantity because charge never graduated into the level of vectors or tensors that need both magnitude and direction.

## Does electric current have direction?

Current has a direction. … By convention, the electric current direction is the direction which positive charge would move. In wires, the actual charge carriers are negatively charged electrons. Nonetheless, the convention used for the direction of current is based on the direction which positive charges would move.

## Is electric current a vector?

Electric current is a scalar quantity. Any physical quantity is termed as a vector quantity when the quantity has magnitude and direction. But there are other factors that determine the quantity as vector or scalar quantity.

## What is the quantity of electric current?

The SI unit of electric current is the ampere, or amp, which is the flow of electric charge across a surface at the rate of one coulomb per second. The ampere (symbol: A) is an SI base unit Electric current is measured using a device called an ammeter.

## Is electric current a derived quantity?

The units of a derived physical quantity are called derived quantity. … Examples of fundamental quantity are mass, length, electric current, temperature, amount of substance, and luminous intensity. Area, speed, velocity, etc are examples of the derived physical quantity.

## Is electric current a tensor quantity?

Current is a scalar. Current density is a vector. Because scalars and vectors are tensors this means current and current density are both tensors.

## Is conductivity a scalar or vector quantity?

Conductance is scalar quantity.

## What is scalar and vector quantity?

A quantity that has magnitude but no particular direction is described as scalar. A quantity that has magnitude and acts in a particular direction is described as vector.

## Is electric current a fundamental quantity?

Thus current is considered as the fundamental physical quantity and charge is a derived quantity.
