Millivoltage

Millivoltage refers to a unit of electrical potential difference, or voltage, that is equal to one-thousandth of a volt. The prefix "milli-" is a standard SI prefix denoting a factor of 10⁻³. Therefore, one millivolt (mV) is equivalent to 0.001 volts (V).

This unit is commonly used when dealing with very small voltage signals, which are prevalent in various scientific and electronic applications. For instance, in electronics, operational amplifiers and sensor outputs often generate signals in the millivolt range. Medical devices also frequently measure and display biological electrical signals, such as electrocardiogram (ECG) readings or electroencephalogram (EEG) waveforms, in millivolts due to their typically low amplitude.

The ability to accurately measure and work with millivoltage is crucial in fields like sensitive instrumentation, bioelectronics, and low-power circuit design. Specialized equipment such as sensitive multimeters or oscilloscopes are designed to detect and display these minute voltage variations. Understanding millivoltage is fundamental to comprehending the behavior of many electronic circuits and biological systems.
