The current density is the current moving through an infinitesimal cross-sectional area divided by the area. To calculate the current density, divide the current passing through the area by the cross-sectional area.
The current density is the current moving through an infinitesimal cross-sectional area divided by the area. It is defined as the flow of charge through an infinitesimal area, taking into account the local magnitude and direction of the charge flow. The current density is a vector quantity and its unit is ampere per meter squared.
To calculate the current density, you need to know the current passing through the area and the cross-sectional area. The current is given as 0.87 A and the cross-sectional area is calculated to be 5.26 mm². To find the current density, divide the current by the area.
Current Density = Current / Area
Current Density = 0.87 A / 5.26 mm²
Current Density ≈ 0.165 A/mm²
The probable question may be:
How is current density defined, and can you demonstrate how to calculate it using a specific example with a current of 0.87 A passing through a cross-sectional area of 5.26 mm²?
