Electric Current Density
Current density, abbreviated as J, is the measure of current per unit of cross section.
Current Density Formulas
\(\large{ J = \frac{I}{A} }\) | |
\(\large{ J = \frac{ E }{ G } }\) |
Where:
Units | English | SI |
\(\large{ J }\) = current density | \(\large{I\;R}\) | \(\large{V}\) |
\(\large{ A }\) = cross-section area of the conductor | \(\large{in^2}\) | \(\large{m^2}\) |
\(\large{ I }\) = current through the conductor | \(\large{\frac{V}{R}}\) | \(\large{I}\) |
\(\large{ G }\) = electric conductivity | - | \(\large{\frac{S}{m}}\) |
\(\large{ E }\) = electric field | - | \(\large{\frac{V}{m}}\) |
