Batteries, current, and Ohm''s law
The voltage of a battery is also known as the emf, the electromotive force. This emf can be thought of as the pressure that causes charges to flow through a circuit the battery is part of. This flow of charge is very similar to the flow of other things, such as heat or water. A flow of charge is known as a current.

Does current continue to run after a capacitor has been charged
The capacitor starts to charge. From my understanding, this is a short circuit at first so no current will flow to the resistor. However, after charge builds up on the capacitor, current will start to flow to the resistor. When the capacitor is fully charged and has a pd equal to the emf of the battery, will the current still flow through the

Complete Electrical Circuits: How Current Flows
A complete circuit is a continuous path that allows electrical current to flow from a source, through components, and back to the source. It consists of a source of voltage (e.g., battery), conductive elements (e.g., wires), and a load (e.g., resistor) that consumes energy. Current flows from the positive terminal of the source, through the load, and returns to the

$begingroup$ @StefanH The final answer to this question is, that there is no electron current flowing through the battery when it is discharging through an electric load circuit. There is only charge displacement via the connected circuit from the negative plate of the battery to the positive plate until the two potentials are equalized and voltage across the battery
5.2: Electric Current
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.

When an ideal capacitor is charged by a d.c. battery, no current flows
When an ideal capacitor is fully charged by a d.c. battery, the electric field E between the plates of capacitor does not change with time. Therefore, displacement current is zero. when an a.c. source is applied between the plates of an ideal capacitor, the electric charge on plates and consequently electric field E between the plates of capacitor is continuosly
When A 12V Battery Causes Charge To Flow: Exploring Current
The battery''s voltage drives the current, influencing how much charge flows through the circuit per unit time.

What happens when a battery is charged?
When a circuit is complete, the battery enables devices to function by providing power. Charging a battery reverses this process. During charging, current flows into the positive terminal, restoring the battery’s chemical potential energy.
How does current flow in a battery?
Current flows from the positive terminal to the negative terminal in a battery. In electrical terms, this is known as conventional current flow. This flow is defined by the movement of positive charge. Electrons, which carry a negative charge, actually move in the opposite direction, from the negative terminal to the positive terminal.
How does a battery charge and discharge?
Charging and Discharging Processes: Current flow reverses during the charging process. A battery is recharged by applying external voltage, prompting the current to flow in the opposite direction. This process restores the original chemical compositions at the electrodes, allowing the battery to be used again.
