millivolt
Definition
- Noun:
- A unit of electrical potential equal to one thousandth of a volt: A "millivolt" is a metric unit used to measure very small electrical potential differences or electromotive forces. It is a subunit of the volt, the standard unit of electric potential in the International System of Units (SI).
Usage Examples
- Noun:
- The sensor detected a signal of only a few millivolts.
- The potential difference across the neuron's membrane is measured in millivolts.
- One millivolt is equal to 0.001 volts.
Advanced Usage
- Scientific and Engineering Context: The term "millivolt" is primarily used in technical fields such as electronics, electrophysiology, and electrical engineering to quantify small voltages that are not conveniently expressed in whole volts.
- The amplifier is sensitive enough to measure changes in the microvolt to millivolt range.
Variants and Related Words
- Volt (n): The base SI unit of electric potential, electromotive force, and voltage. One volt is equal to 1,000 millivolts.
- Microvolt (n): A unit of potential equal to one millionth of a volt (0.000001 V). It is a smaller subunit than the millivolt.
- Kilovolt (n): A unit of potential equal to one thousand volts. It is a larger multiple of the volt.
- Millivoltmeter (n): A measuring instrument designed to measure electrical potential in millivolts. (Note: This is a compound word listed here as a related term).
Synonyms
- mV: The standard abbreviation for millivolt.
- One-thousandth of a volt: A descriptive synonym.
Related Phrases and Abbreviations
- mV: This is the universally accepted symbol for millivolt, used in circuit diagrams, data sheets, and scientific writing.
- The output is 50 mV peak-to-peak.
Noun
-
