2. Is the same as the outside value.

Explanation:
The current inside a copper voltameter is the same as the outside value.An electric current is a flow of electric 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.
