## What is Nernst?

In this app, you can calculate either the Nernst potential (equilibrium potentials of a given ion), or the membrane potential when more than one ion contributes to the potential using the Goldman-Hodgkin-Katz (GHK) equation.

## Key features

- Nernst potential calculation
- Goldman-Hodgkin-Katz equation solver
- Membrane potential calculation
- Ion equilibrium potential calculation
- Educational tool for electrophysiology


## Frequently asked questions about Nernst

### What is the Nernst-GHK Calculator used for?

The Nernst-GHK Calculator is used to compute the Nernst potential, which represents the equilibrium potential for a single ion, and the Goldman-Hodgkin-Katz (GHK) potential, which calculates the membrane potential when multiple ions are involved.

### What is the learning methodology of Nernst-GHK Calculator?

This application provides a direct computational tool for understanding electrophysiological principles. It allows users to input ion concentrations and parameters to see the resulting potentials, aiding in practical application of theoretical knowledge.

### How does Nernst-GHK Calculator track progress?

As a calculation tool, Nernst-GHK Calculator does not have a formal progress tracking system. Users can, however, save their calculations or re-run them to compare different ion conditions and observe changes in potential.

### Does Nernst-GHK Calculator offer certifications?

No, the Nernst-GHK Calculator does not offer any formal certifications. It is designed as an educational aid for learning and performing specific scientific calculations.

### What devices is Nernst-GHK Calculator compatible with?

Nernst-GHK Calculator is available for iPhone and iPod devices. It runs on iOS and is designed to be accessible on these platforms.
