Answer:
Electric current is the flow of electrons and they carry negative charge so electrons inside an atom repels the flow where as a proton attracts the flow.
Explanation:
- Electricity is the process of flow of electrons. During the flow these electrons share bonds or even transfer them.
- These electrons get energy when the potential difference is applied to a conductor that is moving in the direction from low to high therefore, the electrons move from one to another creating electricity.
- Though the electron repels the continuous flow but proton develops the force of attraction.
