The Drift Current Density for free electrons is the current passing through a square centimeter area perpendicular to the direction of flow. The following formula is used to calculate the drift current density: `J_n=qnmu_nE`, where: 

• `q` = charge of an electron 1.6 * 10^-19 C
• `n` = number of free electrons per cubic centimeter
• `mu_n` = mobility of electrons in cm²/V*s
• `E` = applied electric field intensity in V/m
