15mV

15mV refers to a voltage measurement of fifteen millivolts. A millivolt is one-thousandth of a volt, the standard unit of electric potential difference. In practical terms, 15mV represents a relatively small voltage.

This magnitude of voltage is commonly encountered in various electrical and electronic contexts. For instance, it can be the typical output of certain types of sensors, such as thermocouples or some biological signal amplifiers, before being further processed. In audio systems, low-level signals, like those from a turntable's cartridge, are often measured in millivolts. Amplification stages in electronic circuits might operate with signals in this range.

While 15mV is a small voltage, it is still significant enough to be detected and utilized by sensitive electronic components. It is important to distinguish millivolts from volts or kilovolts, as the scale of electrical potential differs greatly. The context in which 15mV is mentioned is crucial for understanding its specific significance and application. For example, in power delivery, 15mV would be negligible, but in signal processing, it could be a meaningful measurement.
