More about: Nernst Equation

What it calculates

The “Nernst Equation” calculator computes E in V from 4 parameters: e° (V), n (electrons), q, t (K).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters E° = 1.1 V, n (electrons) = 2, Q = 0.1, T = 298 K the result is 1.13 V (E = E° − RT/(nF)·lnQ).
