“The ions transport current through the electrolyte while the electrons flow in the external circuit, and that’s what generates an electric current.” If the battery is disposable, it will produce electricity until it runs out of reactants (same chemical potential on both electrodes).
The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens. The wire just gets very hot and the battery loses stored internal energy – it ‘goes flat’ and stops working.
When a battery is connected to an external circuit, such as a flashlight, the electrons flow from the negative electrode to the positive electrode, producing an electric current. This process is called oxidation-reduction (or redox for short). The chemical reactions inside the battery generate an electric current when connected to an external circuit.
This is exactly what happens in an electric battery. When a conducting wire is connected between the positive and negative terminals of a battery, one end of the wire becomes positively charged and the other end negatively charged.
With this analogy, it is plainly obvious why both the positive and negative ends of a battery must be connected in a circuit. If, say, you connect only the negative electrode to ground, there is no current because there is no electricity coming in on the positive electrode that can be pumped out.
When a conducting wire is connected between the positive and negative terminals of a battery, one end of the wire becomes positively charged and the other end negatively charged. The difference in charge causes electrons to move through the wire towards the positive terminal of the battery, where they are removed from the wire.
In lower-voltage batteries, a current moves more slowly (with less electrical force) out of the battery than in a battery with a higher voltage (more electrical force). The …
