Current intensity (strength)
$$I = \frac{e^{2}\cdot n0\cdot t\cdot S\cdot U}{2\cdot m\cdot l}$$
I - current intensity
e - electron charge
n0 - electron concentration
t - time
S - cross-sectional area
U - voltage
m - mass
l - length
e - electron charge
n0 - electron concentration
t - time
S - cross-sectional area
U - voltage
m - mass
l - length
