coulombmeter
Definition
- Noun:
- An instrument for measuring electric charge: A coulombmeter is a device that measures the quantity of electricity (in coulombs) that passes through a circuit over a period of time. It is also known as a coulometer.
Usage Examples
- (The device measured the electric charge in coulombs.)
- (It measures the amount of electrical charge stored or delivered.)
Advanced Usage
- "Coulombmeter" can be used in electrochemistry to quantify the amount of substance produced or consumed during an electrolytic reaction, based on the charge passed.
- By integrating the current over time, the coulombmeter provides an accurate reading of the total charge. (It measures charge through current integration.)
