What is used to measure charges according to Coulomb's law?
Ohmmeter
Coulombmeter
Voltmeter
Wattmeter
Answer
A coulombmeter, the device used to measure electric charge according to Coulomb's law, operates on the principle of measuring the amount of charge flowing through a circuit. It functions by converting the electric charge into a measurable quantity, typically in units of Coulombs (C).
