megavolt
Definition
- Noun:
- Unit of electrical potential: "megavolt" is a unit of electromotive force or electric potential equal to one million volts. It is commonly used in contexts involving high-voltage power transmission, particle accelerators, or lightning.
Usage Examples
- (A very high electrical potential for long-distance transmission.)
- (A machine that generates one million volts for research.)
Advanced Usage
"megavolt range": refers to voltages measured in millions of volts.
- Lightning strikes can produce voltages in the megavolt range. (The electrical discharge of lightning often exceeds one million volts.)
"megavolt-ampere" (MVA): a unit of apparent power in electrical systems, combining voltage and current.
- The transformer is rated at 100 megavolt-amperes. (It can handle 100 million volt-amperes of power.)
Variants and Related Words
Megavoltage (n): the level or magnitude of voltage measured in megavolts.
- The megavoltage of the X-ray machine is calibrated for medical imaging. (The voltage level is set in millions of volts.)
Megavoltmeter (n): an instrument for measuring voltages in the megavolt range.
- The technician used a megavoltmeter to check the high-voltage line. (A device designed for measuring millions of volts.)
Synonyms
- Million volts: a direct equivalent (e.g., ).
- High voltage: a broader term for electrical potential above typical levels (often used for voltages in the kilovolt or megavolt range).
