Electric charge is measured in which of the following units?

Electric charge is measured in coulombs, which is the standard SI unit of electrical charge. One coulomb is defined as the amount of charge that is transferred by a constant current of one ampere in one second. This foundational unit allows for the quantification of how much electric charge is present in a given system, making it essential for calculations involving electrical circuits and phenomena.

Joules measure energy, amperes measure current (the flow of electric charge), and ohms measure resistance (how much a material opposes the flow of current). Each of these units serves a distinct purpose in the field of electricity and electronics, but when it comes specifically to measuring electric charge, coulombs is the correct and applicable unit.
