carbon rod
No, it is the carbon
In a dry cell, the carbon rod is the positive terminal, or anode.
The shortage of electrons exists at the positive terminal of a dry cell. These positive terminals attract electrons, creating a flow of current from the negative terminal to the positive terminal through an external circuit.
When a dry cell is connected in a series, the flow of electrons moves from the negative terminal to the positive terminal. Electrons are negatively charged particles and are attracted to the positive terminal while repelled by the negative terminal. This movement creates an electric current that flows through the circuit.
The positive terminal of a dry cell battery typically identifies the location of the carbon rod, which acts as the positive electrode in the battery. When the battery is connected in a circuit, it is the positive terminal that attracts electrons from the external circuit, facilitating the flow of current within the battery.
when it works it has copper sulfate solution inside the wet cell battery which takes the electrodes from the negative terminal (-) to the positive terminal (+).
They move from the positive to the negative. There are more specific answers to this question so I recommend that you read several of the answers that are offered.
A dry cell produces direct current (DC) when a chemical reaction within the cell generates a flow of electrons in one direction. This current flows from the negative terminal to the positive terminal of the cell.
dry cell - a small Leclanche cell containing no free liquid; the electrolyte is a paste and the negative zinc pole forms the container of the cell; used in flashlights, portable radios, etc
It could blow up the battery.
Current doesn't flow inside the cell. The cell is used to push current through an external circuit. The so-called "conventional" current flows out of the positive terminal of the cell, through the circuit, and back into the negative terminal of the cell. The confusing truth is that the actual physical carrier of current is the electron, which carries a negative charge. So the things that are actually moving and carrying the current through the circuit leave the dry cell from its negative terminal, physically flow through the circuit, and end up at the cell's positive terminal.
When the switch is closed, the stored chemical energy in the dry cell is converted into electrical energy. This allows the flow of electrons from the negative terminal to the positive terminal through the external circuit, allowing devices to operate.
