An ampere (A), also known as ‘amp’, is a unit of electrical current equal to the flow of one coulomb per second. It is named after Andre-Marie Ampere who is widely regarded as the leading pioneer of electrodynamics.
Measuring amperes is important when working with electrical systems as a means of ensuring that the wires are not handling a higher current than they are rated for, and therefore risking faults or failure.
Amperes can be measured using a digital multimeter, but since models differ according to the amount of current they can measure, care should be taken to make sure a device with the correct rating is used.
