# plasmapy.analysis.swept_langmuir.floating_potential¶

Functionality for determining the floating potential of a Langmuir sweep.

## Functions¶

 find_floating_potential(voltage, current[, …]) Determines the floating potential ($$V_f$$) for a given current-voltage (IV) curve obtained from a swept Langmuir probe. find_vf_(voltage, current[, threshold, …]) Alias to find_floating_potential().
