By whose movement the electric current flows in the conductor ?

Options

A. Atoms
B. Protons
C. Electrons
D. Neutrons

Explanation

To answer the question "By whose movement does the electric current flow in the conductor?", we can break down the explanation into clear steps:

### Step-by-Step Solution:

1. **Understanding the Structure of a Conductor**:
- A conductor is made up of atoms, which are electrically neutral. Each atom contains protons (positively charged) and neutrons (neutral) in its nucleus, while electrons (negatively charged) revolve around the nucleus.

2. **Role of Electrons in Conductors**:
- In a conductor, the outer electrons are not tightly bound to the nucleus and can move freely. These free electrons are responsible for conducting electricity.

3. **Connecting a Battery**:
- When a conductor is connected to a battery, a potential difference is created. The battery has a positive terminal and a negative terminal.

4. **Movement of Electrons**:
- The negative terminal of the battery repels the electrons in the conductor, while the positive terminal attracts them. This causes the free electrons to move towards the positive terminal.

5. **Direction of Electric Current**:
- Although the electrons move towards the positive terminal, the conventional direction of electric current is considered to flow from the positive terminal to the negative terminal. This is because current is defined as the flow of positive charge.

6. **Conclusion**:
- Therefore, the flow of electric current in a conductor is due to the movement of electrons.

### Final Answer:
The electric current flows in the conductor due to the movement of electrons.
