## When all parts of a circuit are composed of conducting materials, the circuit is said to be closed. To determine if a circuit is closed, you can follow these steps:

1. Inspect the circuit diagram or physical layout of the circuit to identify all the components, such as wires, resistors, and switches.

2. Make sure all the components are connected in a continuous loop or path. This means that there should be no breaks or gaps in the circuit.

3. Check that all connections are properly secured, and there are no loose or disconnected wires.

4. Verify that the conducting materials used in the circuit, such as metal wires, have low resistance to allow the flow of electric current.

If all these conditions are met, then the circuit is closed. A closed circuit allows an uninterrupted flow of electric current, enabling the circuit to function properly.

Regarding the second question, when an electric current flows through a conductor, each free electron moves. This movement of electrons creates the flow of electric current. In a conducting material, such as a metal wire, free electrons are loosely bound to their atomic nuclei and can move relatively freely under the influence of an applied electric field. The motion of these free electrons is what carries the electric charge and constitutes the current in the conductor.
