What is Cell voltage?

Definition 47.5 School Chemistry — Grades 1 to 12 · Chapter 47 — Electrochemical Cells and Electrolysis

The cell voltage is the voltage measured between the terminals of a cell delivering no current (open circuit), with a voltmeter; it is positive when the voltmeter’s positive terminal is on the cathode.

Examples

Example 47.6 (The Daniell cell)

With both solutions at 1 mol/L1\,\mathrm{mol}/\mathrm{L}, the Daniell cell gives 1.10 V1.10\,\mathrm{V}. How such a voltage is predicted from tables of electrode potentials is shown in the Year 1 volume.
