get_floating_potential
- plasmapy.diagnostics.langmuir.get_floating_potential(probe_characteristic, return_arg: bool = False)[source]
Implement the simplest but crudest method for obtaining an estimate of the floating potential from the probe characteristic.
- Parameters:
probe_characteristic (
Characteristic
) – The probe characteristic that is being analyzed.return_arg (
bool
, optional) – Controls whether or not the argument of the floating potential within the characteristic array should be returned instead of the value of the voltage. Default is False.
- Returns:
V_F – Estimate of the floating potential in units convertible to V.
- Return type:
Notes
The method used in this function takes the probe current closest to zero Amperes as the floating potential.
