Voltameter - Wikipedia
网页A voltameter or coulometer is a scientific instrument used for measuring electric charge (quantity of electricity) through electrolytic action. The SI unit of electric charge is the coulomb . The voltameter should not be confused with a voltmeter , which measures electric potential.
Voltmeter - Wikipedia
网页A voltmeter is an instrument used for measuring electric potential difference between two points in an electric circuit. It is connected in parallel. It usually has a high resistance so that it takes negligible current from the circuit.
