What occurs at the terminals of a battery that enables it to maintain a flow of current?
Understand the Problem
The question is asking about the mechanisms that allow a battery to maintain a flow of current, particularly focusing on the conditions at the battery's terminals.
Answer
Chemical reactions at electrodes maintain current flow in a battery.
Chemical reactions at the electrodes enable a battery to maintain a flow of current by creating a potential difference between the cathode and anode.
Answer for screen readers
Chemical reactions at the electrodes enable a battery to maintain a flow of current by creating a potential difference between the cathode and anode.
More Information
Batteries work through electrolyte-mediated chemical reactions that drive electrons from the anode to the cathode. Connecting a circuit enables these electrons to flow, generating electrical energy for devices.
Tips
It is a common mistake to assume that the flow of current is just about electrons moving freely without a chemical reaction. Understanding the electrochemical process is crucial.
