Respuesta :
When a battery discharges the current exits through the positive terminal at a higher potential than it entered.
- When a battery discharges the current exits the battery through the positive terminal as a circuit connected to that should conduct current from positive to a negative potential.
- Accordingly, the current enters the battery at its negative terminal.
- In practicality, batteries contain some internal resistance that restricts the current flow during current flow.
- That is why there is a potential difference between the 2 terminals.
- To drive the current through the external circuit connected to the battery, it keeps a higher potential at its positive terminal while the negative terminal is kept at a lower potential in contrast.
