Current Density to Current Calculator:
Enter the values of current density, J(A/m2) and cross-sectional area, A(m2) to determine the value of Current, I(A).
Current Density to Current Calculator Formula:
Current density is the measure of electric current flowing per unit area of a cross-section through which the current flows.
Managing current density is critical to avoid excessive heat generation, which could damage components or reduce the efficiency of electrical systems. By keeping current density within safe limits, systems operate reliably and efficiently.
Current density is a vector quantity representing the electric current per unit area of cross-section in a conductor. Electric current is the flow of electric charge through a conductor. This is the area of the conductor through which the current flows.
Current, I(A) in amperes is calculated by dividing the current density, J(A/m2) in amperes per metre square by cross-sectional area, A(m2) in metres square.
Current, I(A) = J(A/m2) * A(m2)
I(A) = current in amperes, A.
J(A/m2) = current density in amperes per metres square, A/m2.
A(m2) = cross-sectional area in metres square, m2.
Current Density to Current Calculation:
- Calculate the current for a conductor with a current density of 500 A/m2 and a cross-sectional area of 0.02 m2.
Given: J(A/m2) = 500A/m2, A(m2) = 0.02 m2.
Current, I(A) = J(A/m2) * A(m2)
I(A) = 500 * 0.02
I(A) = 10A.
- Suppose a conductor has a current of 15 amperes and a cross-sectional area of 0.05 m2. Calculate the current density.
Given: I(A) = 15A, A(m2) = 0.05 m2.
Current, I(A) = J(A/m2) * A(m2)
J(A/m2) = I(A) / A(m2)
J(A/m2) = 15 / 0.05
J(A/m2) = 300A/m2.
