Current Density Formula
The following formula is used to calculate a current density.
j = p*v
- Where j is the current density (A/m^2)
- p is the charge density
- v is the velocity of the charges
Current Density Definition
A current density is defined as the total current per unit of volume or area.
Current Density Example
