electric current is scalar or vector quantity

Question

Answer

It's a Scalar quantity

Answer

Electric current has both magnitude and direction so ideally it should be a vector. But it's a scalar just because it does not follow vector addition.

Answer

Scalar quantity

Answer

It is a scalar quantity.

It has both direction and magnitude but it does not follow triangle law of addition in vectors.

Current added in any direction will always cause increase in current.

Hope it helps.

Answer

It has direction but it doesnot satisfy law of vactor so scaler

Answer

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. If the physical quantity obeys the laws of vector addition such as triangle law of vector addition and parallelogram law of vector addition, then the quantity is said to be a vector quantity.

In the case of electric current, when two currents meet at a junction, the resultant current of these will be an algebraic sum and not the vector sum. Therefore, an electric current is a scalar quantity although it possesses magnitude and direction.

Electric Current: Scalar or Vector Quantity

Electric Current is a Vector Quantity

Definition:
- Electric current is the flow of electric charge in a conductor. It is measured in amperes and is represented by the symbol 'I'.

Scalar vs. Vector Quantity:
- A scalar quantity is defined by its magnitude only, while a vector quantity has both magnitude and direction.
- Electric current is a vector quantity because it has both magnitude (the amount of charge flowing per unit time) and direction (the direction of flow of the charge).

Direction of Current:
- The direction of electric current is defined as the direction in which positive charges flow. Conventionally, the direction of current is taken as the opposite direction to the flow of electrons, which are negatively charged.

Vector Representation:
- In vector representation, the magnitude of the current is represented by the length of the vector, and its direction is indicated by an arrow pointing in the direction of the current flow.

Mathematical Properties:
- When dealing with electric currents in circuits, vector addition and subtraction are often used to determine the net current flowing through a component.

Conclusion:
- In conclusion, electric current is a vector quantity as it possesses both magnitude and direction. Understanding current as a vector is crucial in analyzing and solving problems in electrical circuits.
