Current Density Frequently Asked Questions
What is current density?
The rate of charge flow across any cross-section of any conductor is referred to as current density of the conductor.
Is current density scalar or vector quantity?
Current Density is a vector quantity as it has both magnitude and direction.
What is the current density formula?
The current density of any material is measured with the formula,
J = I/A
Why current density is a vector density?
Current density has both magnitude and direction and thus it is a vector quantity as vector quantities have direction.
What is current?
The rate of flow of electric charge through a conductor is defined as the electric current. It can be classified as,
- Direct Current
- Alternating Current
Current Density
Current Density is defined as the amount of current flowing through the per unit area of the wire. It is measured in ampere/m2. Before learning more about current density we have to learn about current.
Current is defined as the flow of the electron in a wire under a voltage difference. Current is the most common type of energy used in our daily life it provides electrical energy which is responsible for the working of all the electrical appliances which we used in our daily life.
In this article, we will learn about current density, its formula, derivation with brief introduction of electric current.
