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 would happen if you connected the positive terminals of two batteries?

All voltage is relative, so your reasoning is correct. If you connect two positive but non-equal voltage nodes together, current will flow between them. Calling something positive only means that it has a higher voltage potential than something else which you are using as a ground reference.

What do you think will happen if you connect either the positive sides and the negative sides of the batteries together?

Just connecting the positive terminals together doesnt going to do anything. Since without the ground or negative terminal open the circuit is incomplete. 2 Circuit should be closed. If you connects only positive terminals and negative remains open then no current will flow as the circuit is open .

When two cells are joined to form a battery their positive terminal should be connected to each other?

The positive terminal (+) of one cell should always be connected to negative terminal (-) of another cell. But in case of above circuit both the positive terminals are connected to each other.

Do you connect positive to negative?

Each battery has two metal terminals. One is marked positive (+), the other negative (-). Never connect the red cable to the negative battery terminal or a vehicle with a dead battery.

What is the difference between positive and negative terminal in a battery?

Positive and Negative terminals The electrode from which the electrons emerge is the negative terminal. It is also called the cathode. The electrode that receives electrons is the positive terminal. It is called the anode.

What happens if battery is connected backwards?

When a car battery is connected backward, a fuse designed to protect vehicle electronics should blow. If your vehicle doesnt have a fuse (almost all cars do) designed for this purpose, you will send electrical current backward through systems in your car, including ECU, transmission control unit, and more.
