“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).
When a battery or power supply sets up a difference in potential between two parts of a wire, an electric field is created and the electrons respond to that field. In a current-carrying conductor, however, the electrons do not all flow in the same direction.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current. battery: A device that produces electricity by a chemical reaction between two substances. current: The time rate of flow of electric charge.
When current flows through wires in a circuit, the moving charges are electrons. For historical reasons, however, when analyzing circuits the direction of the current is taken to be the direction of the flow of positive charge, opposite to the direction the electrons go. We can blame Benjamin Franklin for this.
The rate at which the charges flow past a location—that is, the amount of charge per unit time—is known as the electrical current. When charges flow through a medium, the current depends on the voltage applied, the material through which the charges flow, and the state of the material.

8.2: Capacitors and Capacitance
When battery terminals are connected to an initially uncharged capacitor, the battery potential moves a small amount of charge of magnitude (Q) from the positive plate to the negative plate. The capacitor remains neutral overall, but with charges (+Q) and (-Q) residing on opposite plates. Figure (PageIndex{1}): Both capacitors shown here were initially …

10.2: Electromotive Force
Introduction to Electromotive Force. Voltage has many sources, a few of which are shown in Figure (PageIndex{2}). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf).The emf is not a force at all, but the term ''electromotive force'' is used for historical reasons.

electrostatics
If you had, say, a resistor in your circuit, then there is an electric field inside the resistor driving the current, so those surfaces orthogonal to the electric field cross through the resistor, and the energy from the battery (or capacitor) actually flows along these surfaces.

How Does Electricity Flow? | Explanation and Review
In our circuits, voltage is the force that moves electric current around. It''s measured in volts (V). Current (I): Current is the flow of electricity. You can imagine it as the amount of water flowing through a pipe. But here, it''s the electric charge that moves in the circuit. We measure current in amperes, often shortened to amps (A).
