This function can calculate any one of the three -
|
|
1. Conductivity
|
|
2. Electron Concentration
|
|
3. Electron Mobility
|
|
This is calculated from the other two provided values
|
|
Examples -
|
|
>>> electric_conductivity(conductivity=25, electron_conc=100, mobility=0)
|
|
('mobility', 1.5604519068722301e+18)

>>> electric_conductivity(conductivity=0, electron_conc=1600, mobility=200)
|
|
('conductivity', 5.12672e-14)
|
|
>>> electric_conductivity(conductivity=1000, electron_conc=0, mobility=1200)
|
|
('electron_conc', 5.201506356240767e+18)
|
|
>>> electric_conductivity(conductivity=-10, electron_conc=100, mobility=0)
