how does a battery provide a potential difference for charge to flow?

Expert Answer:

In battery potential difference is created due to chemical reaction. Due to chemical reaction between the electrode and the electrolyte, one electrode becomes rich in electron i.e. gains -ve polarity, on the other side another becomes +ve polarity. So a potential difference is created which enables charge to flow in the external circuitry.
