Question: What happens when you connect the positive and negative ends of a battery?

What happens if you connect positive to negative on a AA battery? If you connect a wire between the two terminals, the electrons will flow from the negative end to the positive end as fast as they can. This will quickly wear out the battery and can also be dangerous, particularly on larger batteries.

What happens when you connect a positive and negative wire?

If you connect positive to negative directly with a wire, you get a very low resistance circuit. The lower the resistance, the higher the current. The is called a short circuit.

Is it positive to positive battery?

Each battery has two metal terminals. One is marked positive (+), the other negative (-). There are also positive and negative cables in the jumper cable set. The red one is positive (+), the black one is negative (-).
