Is Current a vector quantity?

In summary, vector quantities have both magnitude and direction, while scalar quantities only have magnitude. Current is a vector quantity and can be measured using an ammeter, with the unit of measurement being amperes (A). It can also be negative, indicating a flow opposite to the direction of the arrow representing the current.

Is "Current" a vector quantity?

Is "Current" a scalar quantity? If yes then how? Because what I know is this: "Current is the quantity which has some particular direction i.e. from higher potential electrode to the lower potential electrode. Here it has both magnitude and direction, so it should be a vector quantity".

Current is a vector in electromagnetics/electrodynamics, a scalar in time-dependent circuit theory, and a complex phasor in time harmonic and laplacian (complex frequency) circuit theory.
 

Related to Is Current a vector quantity?

What is a vector quantity?

A vector quantity is a measurement that has both magnitude (size or numerical value) and direction. It is represented by an arrow, where the length represents the magnitude and the direction represents the direction of the measurement.

Is current a vector quantity?

Yes, current is a vector quantity. It is represented by an arrow, where the length represents the magnitude of the current and the direction represents the direction of the flow of the current.

What is the difference between scalar and vector quantities?

Scalar quantities only have magnitude, while vector quantities have both magnitude and direction. Examples of scalar quantities include temperature and speed, while examples of vector quantities include force and velocity.

Can current be negative?

Yes, current can be negative. This indicates that the direction of the current flow is opposite to the direction of the arrow representing the current.

How is current measured?

Current is measured using a device called an ammeter. It is placed in series with the circuit and measures the flow of electric charge through the circuit. The unit of measurement for current is amperes (A).
