Which instrument is used for measuring electric charge?

Explanation:
Electric charge is the amount of electricity that has moved, which relates to how much current flows over time: Q = ∫ I dt. A coulometer is designed to measure that accumulated charge by integrating the current over a period and displaying the total in coulombs. An ammeter only shows instantaneous current (amperes), not the total charge. A voltmeter measures potential difference, and an ohmmeter measures resistance. So the instrument that directly measures electric charge is the coulometer.
