Answer 2

An electric current is a flow ofelectric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma). ... Electric current is measured using a device called an ammeter.
