Question

From which terminal of battery are the electrons taken by the chemical reaction of the battery?

Answer 1

1. Due to the potential difference applied by the battery electrons from the negative terminal of the battery starts to move away from the negative terminal.
2. The movement of the electron is because of the repulsion from the negative terminal as like charges repel each other so, the negative terminal repels the negatively charged electron.
3. So, the electrons move from the negative terminal of the battery to the positive terminal of the battery. When the electrons reach the positive terminal completing the path we get the electric current.
