I think the flow towards positive again to maintain continuous current....hope its helpful...

Understanding Electron Flow in a Circuit
When dealing with electric circuits, it's crucial to understand how electrons behave and the role of the battery in maintaining a continuous current.
Electron Movement to the Positive Terminal
- Electrons flow from the negative terminal of the battery through the circuit towards the positive terminal.
- This movement occurs due to the potential difference created by the battery, which drives the flow of electrons.
Behavior Upon Reaching the Positive Terminal
- Upon reaching the positive terminal, electrons do not simply "stay" there.
- Instead, they enter the battery and participate in a chemical reaction that occurs within the battery.
Flow Through the Battery
- The electrons flow through the internal components of the battery, moving from the positive terminal to the negative terminal.
- This internal movement is essential for re-establishing the potential difference necessary for continuous current flow.
Continuous Current Maintenance
- The chemical reactions in the battery convert stored chemical energy back into electrical energy.
- This process replenishes the electrons, allowing them to flow back into the circuit, thus maintaining a continuous current.
Summary
- Electrons do not remain at the positive terminal; they flow through the battery.
- The battery enables the cycle of electron flow, ensuring that the circuit remains functional and that current continues to flow smoothly.
Understanding this cycle is vital for grasping how electric circuits function effectively.
