Voltmetric

Voltmetric refers to a measurement or characteristic related to voltage. In electronics and electrical engineering, voltmetric often describes phenomena or devices that are dependent on or controlled by voltage. For instance, a voltmetric sensor is a type of sensor whose output signal varies with the applied voltage. This contrasts with amperometric sensors, which measure current.

The term can also be used in the context of analytical chemistry, particularly in electrochemistry. A voltmetric analysis involves measuring the current that flows as a function of applied potential. This technique is used to study redox reactions and determine the concentration of electroactive species in a solution. Different scan rates and waveform shapes can be employed in voltmetric experiments, each providing unique information about the electrochemical system.

In a broader sense, voltmetric describes any aspect of a system that is governed or observed through its voltage behavior. This might include the voltage-dependent behavior of semiconductors, the response of a circuit to voltage changes, or the electrical potential generated by a biological system. Understanding the voltmetric properties is crucial for designing and analyzing electrical and electronic systems.
