Question: 1 / 400

Electric charges, whether moving or at rest, are measured in terms of:

Amperes

Volts

Coulombs

The correct answer is Coulombs, as this unit is specifically used to quantify electric charge. Electric charge refers to the property of matter that causes it to experience a force when placed in an electric and magnetic field. Coulombs measure the amount of electric charge that is contained in particles, such as electrons and protons.

When we talk about moving charges, like current in a circuit, that flow is measured in Amperes, which is the rate of flow of charge. Volts, on the other hand, measure electric potential or voltage, which indicates how much potential energy is available to push charges through a circuit. Ohms measure resistance, which is a material's opposition to the flow of current. Thus, while each of these units pertains to electricity, only Coulombs specifically accepts measurement of electric charge itself.
