An amperometry measures a current at a fixed applied potential, that is at one point on the current-voltage curve. But in voltammetry it records a number of points on, or a chosen region of the current voltage profile. Thus an amperometry is a fixed-potential voltammetry.

Voltammetry is a technique that measures current as a function of applied potential, allowing for the study of electrochemical reactions. Amperometry focuses on measuring current at a fixed potential, often used for detecting analytes based on their electrochemical behavior. In summary, voltammetry involves measuring current as potential changes, while amperometry measures current at a constant potential.

What is amperometry titration?
Amperometry titration is a technique used in analytical chemistry to determine the concentration of a substance in a sample by measuring the current produced during an electrochemical reaction at a working electrode. This method is based on the principle that the current is proportional to the concentration of the analyte being measured. It is often used to quantify a wide range of species, including metal ions, organic compounds, and biological molecules.
How much difference between 2oz and 1.69 oz?

What is the difference between 102 and 103?

What is the difference between a chalkboard and a blackboard?
There is no difference between a chalkboard and a blackboard; they are two different terms used interchangeably to refer to a smooth, dark surface on which you can write with chalk.
If the difference in electronegativity between two atoms is between 0 and 0.5 the bond formed is?
The bond formed is nonpolar covalent if the difference in electronegativity between two atoms is between 0 and 0.5. This means that the electrons are shared equally between the atoms in the bond.
What is the operational difference between polarography and amperometer?
Polarography is a type of voltammetry that measures current at varying potentials to analyze electroactive species, while amperometry measures current at a constant potential to study concentration changes over time. In polarography, the potential is scanned to generate a voltammogram, while amperometry uses a fixed potential to monitor changes in current.
