2. When chemicals in an electric cell are used up, the electric cell stops
producing electricity.
3. In a circuit, current flows from the negative terminal to the positive
terminal of the electric cell.
Answers
Answer:
2.When the chemicals in the electric cell are used up, the electric cell stops producing electricity. The electric cell is then replaced with a new one. In case of rechargeable batteries (such as the type used in mobile phones.
3.The direction of an electric current is by convention the direction in which a positive charge would move. Thus, thecurrent in the external circuit is directed away from the positive terminal and toward the negative terminal of the battery. Electrons would actually move through the wires in the opposite direction.
