sci.goldman-equation Calculator
Calculates the membrane resting potential using the Goldman-Hodgkin-Katz equation, which accounts for multiple ion species and their permeabilities. Typical neuron resting potential is −70 mV, dominated by K⁺ permeability — action potentials depolarise to +30 mV when Na⁺ channels open transiently.
Inputs
Pna Relative
Reference formula or conversion factor shown for context.
Pk Relative
Reference formula or conversion factor shown for context.
Pcl Relative
Reference formula or conversion factor shown for context.
Temperature C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
resting membrane potential (mV)
Sample size or count used in the calculation.
Goldman equation
The value at the specified point or condition.
PK:PNa:PCl ratio
The proportional relationship between two quantities.
